Write Lewis structure of the following compounds and show formal charge on each atom.
The formula for calculation of the formal charge is as follows: -
Formal charge = ½ [total no: of bonding or shared electrons]
Oxygen with single bond will have formal charge of = 6-6-2/2 = -1
Oxygen with double bond will have formal charge of = 6-4-4/2 = 0
Therefore, nitrogen will have a formal charge of = 5-2-6/2 = 0
Oxygen 1 and 4 will have a formal charge = 6-4-4/2= 0
Oxygen 2 and 3 will have a formal charge = 6-4-4/2=0
Hydrogen 1 and 2 will have a formal charge = 1-0-2/2=0
Sulfur will have a formal charge =6-0-12/2 = 0
