Calculate the bond order of ${{\rm{N}}_2},{{\rm{O}}_2}{\rm{,O}}_2^ + $ and ${\rm{O}}_2^ - $
Four diatomic species are listed below. Identify the correct order in which the bond order is increasing in them :
Using molecular orbital theory, compare the bond energy and magnetic character of ${\rm{O}}_2^ + $ and ${\rm{O}}_2^{2 - }$ species.
