Lewis dot structures (or just Lewis structures) were developed around 1920 by pioneering chemist Gilbert Lewis, as a way of picturing chemical bonding in molecules. We draw Lewis structures to. Discover the bonding arrangement of atoms,; Discover whether there is any degeneracy of bonding (more on that later),; Figure out whether a given group of atoms might even bond together to form a.

Sometimes it's difficult to tell which of two possible Lewis structures of a compound represents the actual bonding of the molecule. In those cases we resort to calculating what's called the formal charge of each atom. Formal charge is just a way of bookkeeping that helps us to decide which of multiple Lewis structures is the likely true bonding arrangement of a covalent molecule. The sum of the formal charges, with a couple of extra rules, will help us to decide which of multiple-possible valid Lewis structures is likely to be the correct one. Here's how it's done.

Calculating formal charge

For each atom

Count the number of valence electrons of the neutral atom.

Subtract the number of non-bonding electrons (usually in lone pairs).

Subtract the number of bonds shared by the atom.

Example: CH₄ (methane)

The carbon in CH₄ has four electrons as a neutral atom. It has no lone pairs, and it shares four bonds, so the formal charge is zero. Each hydrogen atom has one electron as a neutral atom, no lone pairs and shares one bond, for a formal charge of zero. All atoms in the molecule have zero formal charge, the 'happiest' situation for any molecule.

Example: H₃C(CO)CH₃, (acetone)

The central carbon has a formal charge of 4 (valence electrons) - 0 (lone pairs) - 4 (bonds) = 0. The oxygen has a formal charge of 6 - 4 - 2 = 0 (same ordering of terms). Each of the methyl (CH₃) carbons has a formal charge of 4 - 0 - 4 = 0
