Explanation:
A formal charge is equal to the number of valence electrons of an atom MINUS the number of electrons assigned to an atom.
Consider the resonance structures for
O
3
.
Oxygen has
6
valence electrons. Look at the top left oxygen atom. It has two lone pairs (
4
electrons) and a double bond (
2
electrons).
Even though a double bond contains
4
electrons total and is counted as such when seeing that oxygen's octet is filled,
2
electrons belong to each oxygen and they are shared among the two.
Let's examine the top resonance structure:

Notice that even though the atoms have varying formal charges, the overall charge of
O

is the sum of the formal charges in the molecule:
