Consider the following electron configuration.

Question

(σ3s)2 (σ3s*)2 (σ3p)2 (π3p)4 (π3p*)4

Select four species that, in theory, would have this electron configuration.

Answer 1

This looks like diatomic species (molecules or ions) of third row elements with 14 electrons. It may be Cl2, SCl-, etc. You should be able to come up with a couple more.
