Expert Answer:

In  formal charge (FC) is the charge assigned to an atom in a molecule and we  assumed that electrons in a chemical bond are shared equally between atoms, regardless of relative electronegativity and the counting of electrons is based on the assumption that the atom in the molecule owns 1 electron of each shared pair and both the electrons of the lone pair.

The formal charge of any atom in a molecule can be calculated by the following equation:

FC = V - L- B/2
where as,
FC=formal charge 
V=Valence electron
L=Lone Pair of electrons
B=Bond pair electrons
