If we combine the spliting schemes the 2s and 2p orbitals. we can predict bon order in all of the diatomic molecules and ions composed of elements in the first complete row of the periodic table remember that only the valence orbitals of the atoms need be considered as we saw in the cases of lithiumhydride and dilithium, the inner orbitals remain tightly bond and retaine there localized atomic character.

following are the rules of building up principle for homonuclear diatomic molecules.

1) The number of molecular orbitals produced is the same as the number of atomic orbitals used to create the(The law of conservation of orbitals).

2) As the overlap between two atomic orbital increases,the difference in energy between the resulting bonding and antibonding molecular orbitals increases.

3) When two atomic orbitalscombine to form a pair of molecular orbitals,the bonding molecular orbitals are stabalized about as much as the antibonding molecular orbitals are destabilized.

4)The interaction between atomic orbitals is greatest when they have the same energy.
