Dear Menka,

Formal charge is way of determining the most probable structure of a molecule. You want a molecule where the formal charges are as close to zero as possible and any negative formal charges on the most electronegative element.

Formal charge = valance electrons minus the nonbonding electrons minus one half of the bonding electrons
FC = VE - NBE - 1/2 BE

The sum of the formal charges will equal zero for a compound or the charge on an ion.

Best Of Luck...!!!!
