$O_{2}^{- 2} (18 e^{-}) : σ 1 s^{2} σ * 1 s^{2} σ 2 s^{2} σ * 2 s^{2} σ 2 p_{x}^{2} π 2 p_{y}^{2} π 2 p_{z}^{2} π * 2 p_{y}^{2} π * 2 p_{z}^{2}; B . O = \frac{10 - 8}{2} = 1$

$O_{2}^{+ 2} (14 e^{-}) : σ 1 s^{2} σ * 1 s^{2} σ 2 s^{2} σ * 2 s^{2} σ 2 p_{x}^{2} π 2 p_{y}^{2} π 2 p_{z}^{2}; B . O = \frac{10 - 4}{2} = 3$

$O_{2}^{+} (15 e^{-}) : σ 1 s^{2} σ * 1 s^{2} σ 2 s^{2} σ * 2 s^{2} σ 2 p_{x}^{2} π 2 p_{y}^{2} π 2 p_{z}^{2} π * 2 p_{y}^{1}; B . O = \frac{10 - 5}{2} = 2.5$

$O_{2}^{-} (17 e^{-}) : σ 1 s^{2} σ * 1 s^{2} σ 2 s^{2} σ * 2 s^{2} σ 2 p_{x}^{2} π 2 p_{y}^{2} π 2 p_{z}^{2} π * 2 p_{y}^{2} π * 2 p_{z}^{1}; B . O = \frac{10 - 7}{2} = 1.5$
