Problem

Which equation gives the formal charge (FC) of an atom in a Lewis structure if V is the number of valence electrons in the free atom, N is the number of non-bonding (lone-pair) electrons assigned to the atom, and B is the number of bonding electrons the atom shares? (a) FC=V−(N+B)\text{FC}=V-(N+B) (b) FC=V−N−B2\text{FC}=V-N-\dfrac{B}{2} (c) FC=V−(N+B)2\text{FC}=V-\dfrac{(N+B)}{2} (d) FC=V−N2−B\text{FC}=V-\dfrac{N}{2}-B
