Vedclass · Answer

(C) The electronic configuration of $Fe$ $(Z = 26)$ is $1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 4s^2, 3d^6$. The $20^{th}$ electron is the second electron entering the $4s$ orbital. For the $4s$ orbital,the principal quantum number $n = 4$,azimuthal quantum number $l = 0$,magnetic quantum number $m_l = 0$,and spin quantum number $m_s = +\frac{1}{2}$ (assuming the first electron is $+\frac{1}{2}$).

The $20^{th}$ electron of $Fe$ $(Z = 26)$ has which of the following sets of quantum numbers?
