Statement I ;  Formal charge of an atom in a molecule (or) ion can be zero.Statement II ;  Formal charge of oxygen in C..≡O.. is -2.

Statement I ;  Formal charge of an atom in a molecule (or) ion can be zero.Ex- In N..H3, Formal charge of ‘N’ = 5-2-3 = 0 ;Statement II ; Formal charge of oxygen in C..≡O.. is +1. Ex- In CO, Formal charge of ‘O’ = 6-2-3 = +1 ;
