To calculate formal charge of three oxygen atom of ozone molecule
Answers

Ozone has a resonance form of O-O=O.
I'm going to give you an equation which is based off of the formal charge equation that I use which makes it quicker to calculate the formal charge when just in need of making a structure.
FC= Row in periodic table - stuff around it (count each electron in lone pairs + bonds)
The left most Oxygen has a formal charge of -1.
It has three pairs of lone pairs, six electrons or "dots" around it (6) and a single bond (1) = 7
FC = 6 - 7 => -1
The middle Oxygen has a formal charge of +1.
One lone pair (2) and a single bond (1) and a double bond (2) = 5
FC = 6 - 5 => +1
The right Oxygen has a formal charge of 0.
Two lone pairs (4) and a double bond (2) = 6.
FC = 6 - 6 => 0
hope it will work fr you......
