I don't know if the answer is $0 or $1,000,000. One part says it's 1,000,000 because it's less than a year, but they also have the intention of using part of it for a long term bond, so I think it could be 0. Below is the question. Other answers to select is 100,...

why is the molecule of Li2^2- a non-existent? this is my reasoning: in the molecule, there is 5 bonding electrons and 3 antibonding electrons. (5-3)/2 gives a bond order of 1, which means the molecule should be diamagentic. please help!
