Can we have a diatomic molecule with its ground state moleculer orbita

1.	Can we have a diatomic molecule with its ground state moleculer orbitals full with electrons ? Give a reason for your answer .
Answer» Solution :No. Becausebond order becomes ZERO, e.g., in CASE of `He_(2), Be_(2), Ne_(2)` , etc . Note that in `H_(2), sigma _(1s)` M.O. is full but`sigma_(1s)^(**)` is EMPTY .
