Nasa's Cassini - Huygens mission detected a large cloud of toxic hydrogen cyanide on Titan, one of Saturn's moons. Titan also contains ethane, acetylene, and ammonia. What are Lewis structures of these molecules? Hcn: + = 10 H 3 CCH 3: + = 14 HCCH: + = 10 NH 3: + = 8 Draw skeleton and connect atoms with single bonds. Remember that H is never central atom: HCN: six electrons located on N H 3 CCH 3: no electrons remain HCCH: no terminal atoms capable of accepting electrons. Nh 3: no terminal atoms capable of accepting electrons. Hcn: no electrons remain H 3 CCH 3: no electrons remain HCCH: four electrons placed on carbon NH 3: two electrons placed on nitrogen where needed to rearrange electrons to form multiple bonds in order to obtain octets on each atom: HCN: form two more C - N bonds H 3 CCH 3: all atoms have correct number of electrons HCCH: form triple bond between two carbon atoms NH 3: all atoms have correct number of electrons carbon soot has been know to man since prehistoric times, but it was not until fairly recently that molecular structure of main component of soot was discover. In 1996, Nobel Prize in Chemistry was awarded to Richard Smalley, Robert Curl, and Harold Kroto for their work in discovering a new form of carbon, C 60 buckminsterfullerene molecule. Entire classes of compounds, including spheres and tubes of various shapes, were discovered based on C 60. This type of molecule, called fullerene, consists of a complex network of single - and double - bond carbon atoms arranged in such a way that each carbon atom obtains full octet of electrons. Because of their size and shape, fullerenes can encapsulate other molecules, so they have shown potential in various applications from hydrogen storage to target drug delivery systems. They also possess unique electronic and optical properties that have been put to good use in solar powered devices and chemical sensors. Xenon is a noble gas, but it forms a number of stable compounds. We examined XeF 4 earlier. What are the Lewis structures of XeF 2 and XeF 6? We can draw the Lewis structure of any covalent molecule by following six steps discussed earlier. In this case, we can condense the last few steps, since not all of them apply. Step 2: Draw skeleton joining atoms by single bonds. Xenon will be the central atom because fluorine cannot be central atom: XeF 2: We place three lone pairs of electrons around each F atom, accounting for 12 electrons and giving each F atom 8 electrons. Thus, six electrons remain. These lone pairs must be placed on Xe atom. This is acceptable because Xe atoms have empty valence shell d orbitals and can accommodate more than eight electrons.

Lewis Symbols of Monoatomic Elements

Thus far in this chapter, we have discussed various types OF bonds that form between atoms and / or ions. In all cases, these bonds involve sharing or transfer OF valence shell electrons between atoms. In this section, we will explore typical methods for depicting valence shell electrons and chemical bonds, namely Lewis symbols and Lewis Structures. Dalton knew OF experiments by French chemist Joseph Proust, who demonstrated that all samples OF pure compound contain same elements in same proportion by mass. This statement is known as law OF Definite Proportions or law OF constant composition. The suggestion that the numbers of atoms of elements in give compound always exist in the same ratio is consistent with these observations. For example, when different samples OF isooctane are analyze, they are found to have a carbon - to - hydrogen mass ratio of OF 5. 33: 1, as show In. It is worth noting that although all samples of a particular compound have the same mass ratio, converse is not true in general. That is, samples that have the same mass ratio are not necessarily the same substance. For example, there are many compounds other than isooctane that also have a carbon - to - hydrogen mass ratio OF 5. 33: 1. 00. Dalton also uses data from Proust, as well as results from his own experiments, to formulate another interesting law. The Law OF Multiple Proportions states that when two elements react to form more than one compound, fixed mass OF one element will react with masses OF other elements in ratio of small, whole numbers. For example, copper and chlorine can form green, crystalline solids with a mass ratio OF 0. 558 g chlorine to 1 g copper, as well as brown crystalline solid with mass ratio OF 1. 116 g chlorine to 1 g copper. These ratios by themselves may not seem particularly interesting or informative; However, if we take the ratio OF these ratios, we obtain a useful and possibly surprising result: small, whole - number ratio. {matheq}\frac{\frac{1.116 \text{ g Cl}}{1 \text{ g Cu}}}{\frac{0.558 \text{ g Cl}}{1 \text{ g Cu}}} = \frac{2}{1}{endmatheq} this can be explained by Atomic Theory if the copper - to - chlorine ratio in the brown compound is 1 copper atom to 2 chlorine atoms, and the ratio in the green compound is 1 copper atom to 1 chlorine atom. The ratio of chlorine atoms is therefore 2 to 1. The earliest recorded discussion of the basic structure of matter came from ancient Greek philosophers, scientists of their day. In the fifth century BC, Leucippus and Democritus argued that all matter was composed of small, finite particles that they called atomos, term derived from the Greek word for indivisible. They think of of atoms as moving particles that differ in shape and size, and which could join together. Later, Aristotle and others came to the conclusion that matter consists of various combinations of four elementsfire, Earth, air, and water could be infinitely divide. Interestingly, these philosophers think about atoms and elements as philosophical concepts, but apparently never consider performing experiments to test their ideas.


Introduction to Lewis Structures for Covalent Molecules

The simplest example to consider is hydrogen, which is the smallest element in periodic table with one proton and one electron. Hydrogen can become stable if it achieves full valence level like the noble gas that is closest to it in periodic table, helium. These are exceptions to the octet rule because they only require 2 electrons to have full valence level. Two h atoms can come together and share each of their electrons to create a covalent bond. A shared pair of electrons can be think of as belonging to either atom, and thus each atom now has two electrons at its valence level, like He. The molecule that results is H 2, and it is the most abundant molecule in the universe. Lewis structure of diatomic hydrogen: this is the process through which H 2 molecule is form. Two h atoms, each contributing electron, share a pair of electrons. This is known as single covalent bond. Notice how two electrons can be found in region of space between two atomic nuclei. The Lewis formalism used for H 2 molecule is H: H or HH. The former, know as the Lewis dot diagram, indicates a pair of shared electrons between atomic symbols, while the latter, know as Lewis structure, uses dash to indicate a pair of shared electrons that form a covalent bond. More complicated molecules are depicted this way as well. Lewis dot dragram for Methane: Methane, with molecular formula CH 4, is show. Electrons are color - cod to indicate which atoms they belong to before covalent bonds form, with red representing hydrogen and blue representing carbon. Four covalent bonds are formed so that C has an octet of valence electrons, and each H has two valence electronsone, from the carbon atom and one from one of the hydrogen atoms. Now consider the case of fluorine, which is found in group VII of the periodic table. It therefore has 7 valence electrons and only needs 1 more in order to have an octet. One way that this can happen is if two f atoms make bond, in which each atom provides one electron that can be shared between two atoms. The resulting molecule that is formed is F 2, and its Lewis structure is FF. After a bond has form, each F atom has 6 electrons at its valence level which are not used to form bond. These non - bonding valence electrons are called lone pairs of electrons and should always be indicated in Lewis diagrams.

Lewis Structures for Polyatomic Ions

Polyatomic ionA charge species are composed of two or more atoms covalently bond, or of metal complex that act as single unit in acid - base chemistry or in formation of salts. Also know as molecular ion. The total number of electrons represented in the Lewis structure is equal to the sum of the number of valence electrons in each individual atom. Non - valence electrons are not represented in Lewis structures. After the total number of available electrons has been determine, electrons must be placed into structure. Lewis structures for polyatomic ions are drawn by the same methods that we have already learned. When counting electrons, negative ions should have extra electrons place in their Lewis structures; positive ions should have fewer electrons than uncharged molecule. When Lewis structure of ion is write, entire structure is placed in brackets, and charge is written as superscript on upper right, outside of brackets. For example, consider the ammonium ion, NH 4 +, which contains 9 - 1 = 8 electrons. One electron is subtracted because the entire molecule has + 1 charge.

The following is an example of how to draw the best Lewis Structure for NO 3 -. First, determine the total number of valence electrons in the molecule. This will be the sum of the group number of all atoms plus charge. Draw skeletal structure for molecule which connects all atoms using only single bonds. Central atom will be one that can form the greatest number of bonds and / or expand its octet. This usually means atom lower and / or to the right in Periodic Table, N in this case. Now we need to add lone pairs of electrons. Of 24 valence electrons available in NO 3 -, 6 were used to make skeletal structure. Add lone pairs of electrons on terminal atoms until their octet is complete or you run out of electrons. If there are remaining electrons, they can be used to complete the octet of the central atom. If you have run out of electrons, you are required to use lone pairs of electrons from the terminal atom to complete octet on the central atom by forming multiple bond. In this case, N is short for 2 electrons, so we can use lone pair from the left of O atom to form a double bond and complete octet on N atom. Now you need to determine FORMAL CHARGES for all of the atoms. Formal charge is calculated by: -, ie see figure below. No Lewis Structure is complete without FORMAL CHARGES. In general, you want: fewest number of FORMAL CHARGES possible, ie FORMAL CHARGES of 0 for as many atoms in structure as possible. Formal CHARGES should match the electronegativity of atom, that is negative CHARGES should be on more electronegative atoms and positive CHARGES on least electronegative atoms if possible. Charges of - 1 and + 1 on adjacent atoms can usually be removed by using lone pair of electrons from - 1 atom to form a double bond to an atom with a + 1 charge. Note: octet can be expanded beyond 8 electrons but only for atoms in period 3 or below in Periodic Table. In our present example, N can not expand beyond 8 electrons so retain FORMAL charge of + 1, but S atom below can expand its octet. You have determined the best Lewis Structure for NO 3 -, but there are a number of ways to show this structure. Although it is most common to use lines to indicate bonding pair of electrons, they can be shown as electrons, see leave most image below. It is also common to show only net charge on ion rather than all of FORMAL CHARGES, ie see right most figure below. Why are there different ways of the same Lewis Structure? It depends what you want to show.

Key Concepts:

If you are required to teach Lewis Dot structures, this short lesson can help you extend what students have learnt about modeling covalent and ionic bonding. Since there is no hands - on activity component, this lesson is not in the 5 - E lesson plan format. There are shorthand ways to represent how atoms form covalent or ionic bonds. Lewis Dot diagrams use dots arranged around atomic symbols to represent electrons at the outermost energy level of the atom. Single bonds are represented by a pair of dots or one line between atoms. Double bonds are represented by two pairs of dots or two lines between atoms. Triple bonds are represented by three pairs of dots or three lines between atoms. Students will be introduced to the basics of Lewis Dot diagrams as they compare energy level models used in chapter 4 to Dot diagrams. Along with teacher, they will review Lewis Dot diagrams for a few common covalent and ionic compounds. Students will be able to interpret and draw Lewis Dot diagrams for individual atoms and both covalent and ionic compounds. The activity sheet serves as formative assessment and gives students practice interpreting Lewis Dot diagrams. Download student activity sheet, and distribute one per student when specified in activity. The Activity sheet will serve as an evaluating component of each 5 - E lesson plan. The model of atom and of covalent and ionic bonding that students have used so far emphasizes attractions between bonding atoms. Nucleus, electrons, and double - head arrows show that protons and electrons from one atom attract oppositely charged electrons and protons from other atom, resulting in bonding. Energy levels show that only valence electrons are involved in bonding. After students understand the important role of attraction of opposite charges, you may introduce them to a common, more symbolic, short - hand way of showing how atoms are bonded together. This information is offered IF you feel that showing students these other models of bonding would be useful or IF you need to cover basic information about Lewis Dot diagrams to satisfy your curriculum.

The Octet Rule

While most elements below atomic number 20 follow the Octet Rule, several exceptions exist, including compounds OF boron and aluminum. The Octet Rule states that atoms below atomic number 20 tend to combine SO that they each have eight electrons in their valence shells, which gives them the same electronic configuration as noble gas. The rule is applicable to main - group elements, especially carbon, nitrogen, oxygen, and halogens, but also to metals such as sodium and magnesium. Valence electrons can be counted using the Lewis electron dot diagram. In carbon dioxide, for example, each oxygen shares four electrons with central carbon. These four electrons are counted in both the carbon Octet and the oxygen Octet because they are share. However, many atoms below atomic number 20 often form compounds that do not follow the Octet Rule. For example, with duet Rule OF first principal energy level, noble gas helium, He, has two electrons at its outer level. Since there is NO 1p subshell, 1s is followed immediately by 2s, and thus level 1 can only have at most two valence electrons. Hydrogen only needs one additional electron to attain this stable configuration, through either Covalent sharing OF electrons or by becoming hydride ion, while lithium needs to lose one by combining ionically with other elements. This leads to hydrogen and lithium both having two electrons in their valence shellthe same electronic configuration as heliumwhen they form molecules by bonding with other elements. There are also a variety of molecules in which there are too few electrons to provide Octet for every atom. Boron and aluminum, from Group III, display different bonding behavior than previously discuss. These atoms each have three valence electrons, So we would predict that these atoms want to bond covalently in order to gain 5 electrons to fulfill the Octet Rule. However, compounds in which boron or aluminum atoms form five bonds are never observe, so we must conclude that simple predictions based on Octet Rule are not reliable for Group III. Consider boron trifluoride. Bonding is relatively simple to model with the Lewis structure if we allow each valence level electron in boron atom to be shared in a Covalent bond with each fluorine atom. In this compound, boron atom only has six valence shell electrons, but Octet Rule is satisfied by fluorine atoms. We might conclude from this one example that boron atoms obey the sextet Rule. However, boron will form stable ion with hydrogen, BH 4 -, in which boron atom do have complete Octet. In addition, BF 3 will react with ammonia, to form a stable compound, NH 3 BF 3, For which Lewis structure can be Draw that shows boron with complete Octet. Compounds OF aluminum follow similar trends. Aluminum trichloride, aluminum hydride, and aluminum hydroxide indicate valence OF three For aluminum, with six valence electrons in bonded molecule.

Electron-deficient Molecules

Another type of exception to Lewis ' approach to bonding is the existence of compounds that possess too few electrons for Lewis ' structure to be write. Such compounds are called electron - deficient compounds. The prime example of an electron - deficient compound is diborane, B 2 H 6. This compound requires at least seven bonds to link its eight atoms together, but it has only 2 3 + 6 1 = 12 valence electrons, which is enough to form only six covalent bonds. Once again, it appears that, as in hypervalent compounds, existence of an electron - deficient compound signifies that a pair of electrons can bond together more than two atoms. Discussion of the quantum mechanical theory of bonding below shows that this is indeed the case. A number of exceptions to Lewis ' theory of bonding have been catalogued here. It has further deficiencies. For example, theory is not quantitative and gives NO clue to how the strength of bonds or their lengths can be assess. In form in which it has been present, it also fails to suggest shapes of molecules. Furthermore, theory offers NO justification for regarding electron pair as central feature of covalent bond. Indeed, there are species that possess bonds that rely on the presence of a single electron. Nevertheless, in spite of these difficulties, Lewis ' approach to bonding has proven exceptionally useful. It predicts when the octet rule is likely to be valid and when hypervalence can be anticipate, and the occurrence of multiple bonds and presence of lone pairs of electrons correlate with chemical properties of a wide variety of species. The Lewiss approach is still widely used as a rule of thumb for assessing structures and properties of covalent species, and modern quantum mechanical theories echo its general content. The following sections discuss how limitations of the Lewis approach can be overcome, first by extending theory to account for molecular shapes and then by developing more thorough quantum mechanical theories of chemical bond.


Lewis Structures

We also use Lewis symbols to indicate the formation of covalent bonds, which are shown in Lewis structures, drawings that describe bonding in molecules and polyatomic ions. For example, when two chlorine atoms form chlorine molecule, they share one pair of electrons: Lewis structure indicates that each atom has three pairs of electrons that are not used in bonding and one share pair of electrons. Dash is sometimes used to indicate shared pair of electrons: single shared pair of electrons is called single bond. Each atom interacts with eight valence electrons: six in lone pairs and two in single bond.


The Octet Rule

Other halogen molecules form bonds like those in chlorine molecule: one single bond between atoms and three lone pairs of electrons per atom. This allows each halogen atom to have a noble gas electron configuration. The tendency of main group atoms to form enough bonds to obtain eight valence electrons is known as the octet rule. The number of bonds that atom can form can often be predicted from the number of electrons needed to reach octet; this is especially true of nonmetals of the second period of the periodic table. For example, each atom of group 14 elements has four electrons in its outermost shell and therefore requires four more electrons to reach the octet. These four electrons can be gained by forming four covalent bonds, as illustrated here for carbon in CCl 4 and silicon in SiH 4. Because hydrogen only needs two electrons to fill its valence shell, it is an exception to the octet rule and only needs to form one bond. Transition elements and inner transition elements also do not follow the octet rule since they have d and F electrons involved in their valence shells. Group 15 elements such as nitrogen have five valence electrons in atomic Lewis symbol: one lone pair and three unpaired electrons. To obtain octet, these atoms form three covalent bonds, as in NH 3. Oxygen and other atoms in group 16 obtain octets by forming two covalent bonds:

They also possess unique electronic and optical properties that have been put to good use in solar powered devices and chemical sensors. Xenon is a noble gas, but it forms a number of stable compounds. We examined {matheq}{XeF4}{endmatheq} earlier. What are the Lewis Structures of {matheq}{XeF2}{endmatheq} and {matheq}{XeF6}{endmatheq} We can draw the Lewis structure of any covalent molecule by following six steps discussed earlier. In this case, we can condense the last few steps, since not all of them apply. {matheq}{XeF6}{endmatheq} 8 + = 50 step 2: Draw skeleton joining atoms by single bonds. Xenon will be the central atom because fluorine cannot be central atom: XeF 2: We place three lone pairs of electrons around each F atom, accounting for 12 electrons and giving each F atom 8 electrons. Thus, six electrons remain. These lone pairs must be placed on Xe atom. This is acceptable because Xe atoms have empty valence shell d orbitals and can accommodate more than eight electrons.


Lewis Structures

For very simple molecules and molecular ions, we can write Lewis structures by merely pairing up unpaired electrons on constituent atoms. See these examples: For more complicated molecules and molecular ions, it is helpful to follow the step - by - step procedure outlined here: determining total number of valence electrons. For cations, subtract one electron for each positive charge. For anions, add one electron for each negative charge. Draw skeleton structure of a molecule or ion, arranging atoms around the central atom. Connect each atom to the central atom with a single bond. Distribute remaining electrons as lone pairs on terminal atoms, completing octet around each atom. Place all remaining electrons on the central atom. Rearrange electrons OF outer atoms to make multiple bonds with central atom in order to obtain octets wherever possible. Let us determine Lewis structures OF, and as example in following this procedure: determine the total number OF valence electrons in molecule or ion. For molecule, we add the number OF valence electrons on each atom in molecule: SiH 4 Si: 4 valence electrons / atom 1 atom = 4 + H: 1 valence electron / atom 4 atoms = 4 = 8 valence electrons. For negative ion, we add the number OF valence electrons on atoms to the number OF negative charges on ion: CHO 2 - C: 4 valence electrons / atom 1 atom = 4 H: 1 valence electrons / atom 1 atom = 1 O: 6 valence electrons / atom 2 & atoms = 12 + 1 additional electron = 18 valence electrons For positive ion, such as, we add number OF valence electrons on atoms in ion and then subtract number OF positive charges on ion from total number OF valence electrons: NO + N: 5 valence electrons / atom 1 atom = 5 O: 6 valence electrons / atom 1 atom = 6 + - 1 electron = 10 valence electrons Since is neutral molecule, we simply add number OF valence electrons: OF 2 O: 6 valence electrons / atom 1 atom = 6 + F: 7 valence electrons / atom 2 atoms = 14 = 20 valence electrons Draw skeleton structure OF molecule or ion, arranging atoms around central atom and connecting each atom to central atom with single bond. When several arrangements OF atoms are possible, as For, we must use experimental evidence to choose the correct one. In general, less electronegative elements are more likely to be central atoms. In, less electronegative carbon atoms occupy central position with oxygen and hydrogen atoms surrounding them. Other examples include In, In, and In. An exception is that hydrogen is almost never the central atom. Like most electronegative element,ss fluorine also cannot be central atom. Distribute remaining electrons as lone pairs on terminal atoms to complete their valence shells with octet OF electrons.
