## Molecular Orbital Theory

According to molecular orbital theory, which of the following species is the most likely to exist?

a) $$H_{2}^{-2}$$
b) $$He_{2}$$
c) $$Li_{2}$$
d) $$Li_{2}^{-2}$$
e) $$Be_{2}$$

I think the answer is c), due to it having a bond order of 1, but I just wanted to make sure.

For instance if you find that H2 is more stable then H2-, then there's an incentive to browse some of the other choices.
