According to MOT, two atomic orbitals overlap relsulting in the formation of molecular orbital. Number of atomic orbitals overlapping together is equal to the molecular orbital formed. The two atomic orbital formed by LCAO (linear combination of atomic orbital) in the same phase or in the different phase are known as bonding and antibonding molecular orbitals respectively. theenergy of bonding molecular orbital is less than that of the pure atomic orbital by an amount `Delta`. this is known as the stabilization energy. the energy of antibonding molecular orbital is increased by `'Delta'` (destabilisation energy)
The bond order of `N_(2)^(-)` is equal to that of
