ur question is not complete but i think you want to know about the stability order between Li2 , Li2 + and Li2 -.
See you have to find the bond order by Molecular orbital theory. ok
you have to use the formula B.O. = ½ (N.B – N.A)
N.B is no. of electrons in bonding orbitals and N.A is the no. of e- in antibonding orbitals.
