Formal Way

This sharing of electrons allowing atoms to stick together is the basis of covalent bonding. There are some intermediate distances, generally a bit longer than 0. 1 nm, or if you prefer 100 pm, at which attractive forces significantly outweigh repulsive forces and bond will be formed if both atoms can achieve complete S 2 np 6 configuration. It is this behavior that Lewis captures in his octet rule. Valence electron configurations of constituent atoms of a covalent compound are important factors in determining its structure, stoichiometry, and properties. For example, chlorine, with seven valence electrons, is one electron short of an octet. If two chlorine atoms share their unpaired electrons by making a covalent bond and forming Cl 2, they can each complete their valence shell: each chlorine atom now has octet. An electron pair being shared by atoms is called a bonding pair; other three pairs of electrons on each chlorine atom are called lone pairs. Lone pairs do not involve covalent bonding. If both electrons in a covalent bond come from the same atom, bond is called a coordinate covalent bond. We can illustrate the formation of water molecule from two hydrogen atoms and an oxygen atom using Lewis Dot symbols: structure on right is the Lewis electron Structure, or Lewis Structure, for H 2 O. With two bonding pairs and two lone pairs, oxygen atom has now completed its octet. Moreover, by sharing bonding pair with oxygen, each hydrogen atom now has a full valence shell of two electrons. Chemists usually indicate bonding pair by single line, as shown here for our two examples: following procedure can be used to construct Lewis electron structures for more complex molecules and ions: arrange atoms to show specific connections. When there is a central atom, it is usually the least electronegative element in the compound. Chemists usually list this central atom first in chemical formula, which is another clue to compound structure. Hydrogen and halogens are almost always connected to only one other atom, so they are usually terminal rather than central. Determine total number of valence electrons in molecule or ion. Add together valence electrons from each atom. If a species is a polyatomic ion, remember to add or subtract the number of electrons necessary to give total charge on ion. For CO32−, for example, we add two electrons to the total because of −2 charge. Place bonding pair of electrons between each pair of adjacent atoms to give a single bond. In {matheq}H_2O{endmatheq} for example, there is a bonding pair of electrons between oxygen and hydrogen. Beginning with terminal atoms, add enough electrons to each atom to give each atom an octet. These electrons will usually be lone pairs. If any electrons are left over, place them on the central atom. Some atoms are able to accommodate more than eight electrons.

Finding H 2 O molecular geometry using VSEPR theory is not very difficult using these three steps. Step 1: Draw the Lewis structure for H 2 O using an easy method where you calculate the total valence of electrons in molecule to determine the Lewis structure. You can look at atoms like puzzle pieces where you are trying to fit together electrons so that everyone that needs an octet has one. In this example, oxygen is the central atom. Hydrogen atoms will come off each side of oxygen. Each hydrogen atom must have two electrons. Oxygen will have eight total electrons, meaning it has two bonds and two lone pairs. = Number of central atoms X = Number of surrounding atoms E = Number of lone pairs on the central atom based on the Lewis structure above AXE notation would be AX 2 E 2, meaning there are a total of four substituents coming off of the central atom. Step 3: Use VSEPR table to determine H 2 O electron geometry: four substituents are tetrahedral. While electron geometry is tetrahedral, H 2 O molecular geometry is bent. The bond angle for this molecule is 109 0.
