(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The electron configuration for three neutral atoms are as follows.

A.1s^{2}2s^{2}2p^{3 }

B.1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{5}5s^{2}4d^{7 }

C.1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{6}

Indicate which are valence orbitals.

3. The attempt at a solution
