Q. Consider the ground state of $(Z = 24)$. The numbers of electrons with the azimuthal quantum numbers, $l = 1$ and $2$ are respectively
A) 12 and 4
B) 12 and 5
C) 16 and 4
D) 16 and 5
Explanation
(b)
$Z = (24) = 1s^{2},2s^{2},2p^{6},3s^{2},3p^{6},4s^{1},3d^{5}$
$l = 1$, means $p$-orbitals and $p$-orbitals have total 12 electrons
$l = 2$ means $d$-orbitals and $d -$ orbitals have total 5 electrons
