So why is this structure incomplete? The answer lies in . 2. The Problem of Formal Charge Formal charge is a bookkeeping tool that helps us identify the most stable, plausible Lewis structure. It does not represent a real charge, but rather the electron “ownership” difference between an atom in a molecule and a free atom.

The initial structure (Structure A) looks like this:

We started with 32 electrons. After using 8 for bonds, we have (32 - 8 = 24) electrons left (or 12 lone pairs). Oxygen atoms are greedy for electrons. To satisfy the octet rule, each oxygen needs 6 more electrons (3 lone pairs) around it. (4 \text oxygens \times 6 \text electrons = 24) electrons. Perfect.
