Question
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 $\mathrm{He}_2, \mathrm{Be}_2, \mathrm{Ne}_2$, etc. Note that in $\mathrm{H}_2, \sigma 1 \mathrm{s}$ molecular orbital is full but $\sigma 1 \mathrm{s}$ is empty.
