-O₂ has a bond order of 2 and an antibonding HOMO, meaning it has unpaired electrons and is paramagnetic. -Adding ^2- fills the antibonding HOMO, decreasing the bond order by 1. Therefore, the expected bond order is 1. -Adding ²⁺ fills the antibonding HOMO and creates a new bonding MO, increasing the bond order by 1. Therefore, the expected bond order is 3.
