Vedclass · Answer

(A) The total number of electrons in $O_2^{2-}$ is $18$.The molecular orbital configuration is: $\sigma 1s^2, \sigma^* 1s^2, \sigma 2s^2, \sigma^* 2s^2, \sigma 2p_z^2, \pi 2p_x^2 = \pi 2p_y^2, \pi^* 2p_x^2 = \pi^* 2p_y^2$.Counting the electrons in the atomic orbitals that do not participate in bonding (the inner shell $1s$ and $2s$ orbitals,and the lone pairs in the valence shell),we look at the non-bonding electrons.Specifically,the electrons in the $1s, 2s$ orbitals and the lone pairs in the $O$ atoms contribute to the non-bonding character.In $O_2^{2-}$,there are $16$ non-bonding electrons,which corresponds to $8$ non-bonding electron pairs.
