General Chemistry (Left Column)

1. The bond order for $\text{O}_2^{2-}$ is ---

Determine the total number of valence electrons for $\text{O}_2^{2-}$ .
Each oxygen atom has 6 valence electrons, and the $2-$ charge adds 2 electrons.
Total valence electrons $= (2 \times 6) + 2 = 12 + 2 = 14$ electrons.
Fill the molecular orbitals (MOs) with the electrons.
The MO configuration for 14 electrons is $\sigma_{2s}^
