Why is He2- unstable?

Answers

Answered by Anshchatterjee

you must construct a molecular orbital (MO) diagram for the hypothetical He2 molecule. The σ1s bonding and antibonding orbitals will be full. Calculating the bond order results in 0. In other words, no bond can be sustained between two He atoms according to MO theory.
