WebAug 3, 2014 · Therefore, He2 molecules are not predicted to be stable (and are not stable) in the lowest energy ground state. However, in a high-energy environment, electron (s) from the antibonding orbitals in He2 can be promoted into higher-energy bonding orbitals, thus giving a nonzero bond order and a “reason” to form. chili pods in spanish
