In order to understand fully the structures of N2,N2+,O2 and O2+ we should know the electronic configurations of these species.

N2 and N2+

Molecule of N2 has 10 electrons distributed in bonding and antibonding molecular orbitals as under:

sigma 2s(bonding) 2
sigma 2s (antibonding) 2
pi-2p (bonding) ...

Solution Summary

The solution explains the dissociation energy of neutral nitrogen and oxygen with reference to the MO theory.
