Peroxide ion is

O_{2}^{2 -}

O_{2}^{2 -} (18) = σ 1 s^{2}, σ^{*} 1 s^{2}, σ 2 s^{2}, σ^{*} 2 s^{2}, σ 2 p_{z}^{2}, π 2 p_{x}^{2} = π 2 p_{y}^{2}, π^{*} 2 p_{x}^{2} = π^{*} 2 p_{y}^{2}

Bond order

= \frac{N _{b} - N _{a}}{2} = \frac{10 - 8}{2} = 1

It contains four completely filled antibonding molecular orbitals. Since all the electrons are paired,

O_{2}^{2 -}

is diamagnetic.

Peroxide ion is isoelectronic with argon, not with neon.
