(A) The given quantum numbers $n = 3$,$l = 0$,$m = 0$,$s = -1/2$ correspond to an electron in the $3s$ orbital.For $Mg$ $(Z = 12)$,the electronic configuration is $1s^2 2s^2 2p^6 3s^2$.The two electrons in the $3s$ orbital have quantum numbers $(3, 0, 0, +1/2)$ and $(3, 0, 0, -1/2)$.Thus,the set belongs to $Mg$.
