The number of electrons present in bonding and antibonding orbitals in $\mathrm{O}_2^{2-}$ is respectively
  1. 10,6
  2. 12,6
  3. 11,7
  4. 10,8

Solution


$\begin{aligned} & \left.(\sigma 1 s)^2,\left(\sigma^* 1 s\right)^2,(\sigma 2 s)^2,\left(\sigma^* 2 s\right)^2, \sigma 2 p_z\right)^2, \\ & \left(\pi 2 p_x^2=\pi 2 p_y^2\right),\left(\pi^* 2 p_x^2=\pi^* 2 p_y^2\right)\end{aligned}$
