Homework Help: chemistry

Posted by frustrated on Saturday, October 6, 2007 at 2:19pm.

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!
