# Lewis Dot Structure For Carbon

### General | Latest Info

We use Lewis symbols to describe valence electron configurations of atoms and monatomic ions. Lewis symbols consist of an elemental symbol encircled by a period for each of its valence electrons: figure 1 shows Lewis symbols for elements of the third period of the periodic table. Lewis symbols can also be used to illustrate the formation of cations of atoms, as shown here for sodium and calcium: likewise, they can be used to show formation of anions of atoms, as shown here for chlorine and sulphur: figure 2 shows Lewis symbols use to show electron transfer during the formation of ionic compounds.

### 9.1 Lewis Electron Dot Diagrams

Carbon soot has been known to man since prehistoric times, but it wasnt until very recently that the molecular structure of the major component of soot was discover. In 1996, Nobel Prize in Chemistry was awarded to Richard Smalley, Robert Curl, and Harold Kroto for their work to discover a new form of carbon, C 60 buckminsterfullerene molecule. A full class of compounds, including spheres and tubes of various forms, were discovered based on C 60. This type of molecule, call fullerene, shows promise in a variety of applications. 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 power devices and chemical sensors.

### CO2 Hybridization

Molecular orbital diagram of any composite gives us an idea of bonding of orbitals. It also helps us to find bond order, length of bond, force of molecule fixture. In the diagram, left-hand side consists of atomic orbitals. Likewise, left-hand side has Oxygen AOs. And in the middle is to MO. We can see that 2s Oxygen orbitals are not involved in mixing and remain nonbonding orbital. The reason for this is the high energy difference between Carbon and 2s orbital. All 16 electrons are precisely filled in together as per rules. Bonding orbitals are vacant CO2 case as observed from the MO diagram. Aside from these concepts, we will also study the methods of CO2 gas formation.

Valence electrons are high-energy electrons in the outermost electron shell where the union normally occur. The number of valence electrons can be easily identified by looking at the column in which Atom is located in the periodic table: here, periodic table is cod. Each column corresponds to a certain number of valence electrons. For example, all elements in the red column have 1 valence electron, all orange elements have 2 valence electrons, and so on. Add a number of valence electrons for each Atom in the Molecule to find the total number of electrons. This sum is the number of electrons you must use in the Lewis Dot Structure. We will follow each step of the creation of a carbon Structure of Lewis using CO 2 as example.

### The Octet Rule

For very simple molecules and molecular Ions, We can write Lewis Structures by simply couple unpaired Electrons on constituent atoms. See these examples: For more complicated molecules and molecular Ions, it is useful to follow the passing-by-Step procedure scheme here: determine the total Number OF Valence Electrons. For cations, subtract one Electron For each positive charge. For anions, add an Electron For each negative charge. Draw the structure OF a molecule or ion, arrange atoms around the Central atom. Connect each atom to the Central atom with a Single Bond. Distribute remaining Electrons as unique pair in terminal atoms, round Octet around each atom. Put all remaining Electrons in the Central atom. The rearrange Electrons OF outer atoms to make multiple bonds with the Central atom in order to get octets whenever possible. We determine Lewis Structures OF SiH 4, CHO 2, NO +, and 2 as examples in the following this procedure: determine the total Number OF Valence Electrons in molecule or ion. For molecule, We add the Number OF Valence Electrons in each atom in molecule: {matheq}\begin{array}{r r l} \text{SiH}_4 & & \ {matheq}1em] & \text{Si: 4 valence electrons/atom} \times 1 \;\text{atom} & = 4 \ {matheq}1em] \rule[-0.5ex]{21em}{0.1ex}\hspace{-21em} + & \text{H: 1 valence electron/atom} \times 4 \;\text{atoms} & = 4 \ {matheq}1em] & & = 8 \;\text{valence electrons} \end{array}{endmatheq} For negative ion, such as CHO 2 −, We add the Number OF Valence Electrons on atoms to the Number OF negative charges on ion: {matheq}\begin{array}{r r l} {\text{CHO}_2}^{-} & & \ {matheq}1em] & \text{C: 4 valence electrons/atom} \times 1 \;\text{atom} & = 4 \ {matheq}1em] & \text{H: 1 valence electron/atom} \times 1 \;\text{atom} & = 1 \ {matheq}1em] & \text{O: 6 valence electrons/atom} \times 2 \;\text{atoms} & = 12 \ {matheq}1em] \rule[-0.5ex]{21.5em}{0.1ex}\hspace{-21.5em} + & 1\;\text{additional electron} & = 1 \ {matheq}1em] & & = 18 \;\text{valence electrons} \end{array}{endmatheq} For positive ion, such as NO +, add the Number OF Valence Electrons on atoms in ion and then subtract Number OF positive charges on ion from total Number OF Valence Electrons: {matheq}\begin{array}{r r l} \text{NO}^{+} & & \ {matheq}1em] & \text{N: 5 valence electrons/atom} \times 1 \;\text{atom} & = 5 \ {matheq}1em] & \text{O: 6 valence electrons/atom} \times 1 \;\text{atom} & = 6 \ {matheq}1em] \rule[-0.5ex]{21em}{0.1ex}\hspace{-21em} + & -1 \;\text{electron (positive charge)} & = -1 \ {matheq}1em] & & = 10 \;\text{valence electrons} \end{array}{endmatheq} From 2 is neutral molecule, simply add the Number OF Valence Electrons: {matheq}\begin{array}{r r l} \text{OF}_{2} & & \ {matheq}1em] & \text{O: 6 valence electrons/atom} \times 1 \;\text{atom} & = 6 \ {matheq}1em] \rule[-0.5ex]{21em}{0.1ex}\hspace{-21em} + & \text{F: 7 valence electrons/atom} \times 2 \;\text{atoms} & = 14 \ {matheq}1em] & & = 20 \;\text{valence electrons} \end{array}{endmatheq} Draw structure OF the structure OF the molecule or ion, arranging atoms around Central atom and attach each atom to the Central atom to the unique Bond. When various atom fixes are possible, as For CHO 2 −, We must use experimental evidence to choose the right one. In general, less Electron elements are more likely to be core atoms. In CHO 2 addison, less Electron carbon atoms occupy Central position with oxygen atoms and hydrogen surrounding them. Other examples include P in POCl 3, S in SO 2, and Cl in ClO 4 −. The exception is that hydrogen is almost never a Central atom. As more electronegative element, fluorine, also cannot be the Central atom. Distribute remaining Electrons as the only Pairs in terminal atoms to complete their Valence shells with Electron Octet. 10 because the remaining Electrons as the only pair in terminal atoms to complete their Valence shells with Electron Octet.

### Double and Triple Bonds

In this lesson, you reviewed the basics of the Lewis Dot structure. The Lewis Dot structure can be represented by two points or by one line between two atoms when there is the chemical Bond-two lines for Double Bonds and three lines for Triple Bond. You learn that to write Lewis structure for composites, follow these steps: determine the type and number of atoms on molecule. Type the Lewis Dot structure for each individual atom. Connect atoms per pair of Electron Bonds so that each atom has a full Octet. If you have carbon in your molecule, it is always in the middle. Hydrogens are usually on outside. Double-check your work and ensure that each atom has eight Electrons and NO more.

### Example 1

In many molecules, the octet rule would not be satisfying if each pair of bond atoms shares only two electrons. Review HCN in Step 5 above. Another example is carbon dioxide. CO 2 has a total valence of 4e-+ = 16e-. Following steps 1 to 4, we draw the following: this does not give full carbon atom octet; only four electrons are in their valence shell. This arrangement of share electrons is far from satisfying. In this case, more than one pair of electrons must be shared between two atoms for both atoms to have an octet. The second pair of electrons from each oxygen atom must be shared with the central carbon atom shown by arrows above. The unique pair of each or must be turned into a pair of electrons. In this arrangement, carbon atom shares four electrons with oxygen atom on the left and four electrons with oxygen atom in the right. Now there are eight electrons around each atom. Two electron pairs shared between two atoms make a double bond between atoms, which is represented by double dash: some molecules contain triple bonds. Triple bonds are covalent bonds in which three pairs of electrons are shared by two atoms.
