    Look for two atoms that have the same outer electronic configuration. Ignore the inner orbitals like d.

    Ray, I want you to look at the configurations. [He]2s^2 [Ne] 3s^1 have different outer electronic configs, so they are not the answer. One has 2 outer electrons and one has 1. Now go down the list.
