Which of the following species,$O_2^-$ or $O_2^{2-}$,has a higher bond order?

Assertion : Fluorine molecule has bond order one.
Reason : The number of electrons in the antibonding molecular orbitals is two less than that in bonding molecular orbitals.

The sum of the bond orders of $O_2^{2+}, O_2^{2-}, O_2^{+}, O_2^{-}, O_2$ and the sum of the unpaired electrons present in them respectively are
