 P: 126 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.
 Sci Advisor HW Helper P: 1,769 The point here is probably to have you assess the respective diatomic compound given form (e.g. ion with a 2- charge) with other possibly more stable electron counts. For instance if you find that H2 is more stable then H2-, then there's an incentive to browse some of the other choices.
