The energy-level diagram shown here can be continued to higher energies. The next few orbitals, in order of increasing energy, are σ3s, σ3s, π 3p, σ3p, π 3p and σ3p; in other words, the σ2s to σ2p pattern is repeated. Determine the bond order of a Mg2 molecule.

The bond order of Mg2 molecule is given by:

Mg2 = 4e⁻= 3σs(2e⁻) 3σs(2e⁻) 3σp(0) 3πp(0e⁻) 3πp(0e⁻)
3σp(0e⁻)

Bond Order = ½[Σ (bonding e-) - Σ (antibonding e-)]

bo = ½[ {σs(2e⁻)} - {σs(2e⁻)}] = 0

the bond between Mg2 molecules are ionic bonding and it
stable.
