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

State wether atom is in ground or excited state.

2. Relevant equations

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}

3. The attempt at a solution

A. Ground because all are filled in order.

B.Excited because the 5s sub-shell isnt quite full.

C.Ground as all are filled in order.

Can someone check that i have this correct and if not please explain to me what ive done wrong. Thanks!!
