    Can we have a diatomic molecule with its ground state molecular orbitals full with electrons? Give a reason for your answer.

    Answer:

                    No. Because bond order becomes zero, e.g., in case of \[H{{e}_{2}},\,B{{e}_{2}},\,N{{e}_{2}},\] etc. Note that in \[{{H}_{2}},\,{{\sigma }_{1s}}M.O.\]is full but \[\sigma _{1s}^{*}\]is empty.
