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. Determine the bond of a Mg2 molecule. Predict the stability 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.
