Stability of the species Li 2 , Li 2 - and Li 2 + increases in the order of

Step-by-step solution

  Li 2 - < Li 2 + < Li 2 Bond order ∝ stability of species Li 2 = σ 1 s 2 < σ * 1 s 2 < σ 2 s 2                        ;    B . O = 4 − 2 2 = 1 Li 2 − = σ 1 s 2 < σ * 1 s 2 < σ 2 s 2 < σ * 2 s 1              &#820
