Arrange the three species N₂,  N₂⁺ and N₂^- in the order of

1) Increasing bond length
2) Increasing bond energy

I've calculated the Bond Orders of the three species to be 3,2.5,2.5 respectively. And I think N₂ has the lowest bond length and Highest Bond energy. But how can I compare the other two species?

Thanks in advance

Compare ethane, ethene and ethylene...?

sorry, I didn't get the hint can you please explain

Well, if bond order is the same, then the 2 species should have approximately the same bond length and energy.
