According to molecular orbital theory, the number of unpaired electron(s) in $O_{2}^{2 -}$ is _________ .

Answer:

0.00

Solution:

$O_{2}^{- 2} = 18 e^{-},$ there is no unpaired electron
${(σ 1 s)}^{2} {(σ^{*} 1 s)}^{2} {(σ 2 s)}^{2} {(σ^{*} 2 s)}^{2} {(σ 2 p_{z})}^{2} (π 2 p^{2} x = π 2 p^{2} y) (π^{*} 2 p_{x}^{2} = π^{*} 2 p^{2} y)$
