Formal Charges in Ozone Molecule

The video tutorial explains how to calculate the formal charges on each oxygen atom in an O3 molecule. It begins by examining the Lewis structure and then applies a formula to determine the formal charges for each oxygen atom. The tutorial covers the calculation for the first oxygen with a double bond, the central oxygen with three bonds, and the final oxygen with a single bond. The formal charges are summed to confirm the total charge of the O3 molecule is zero.
