Which of the following sets of quantum numbers could represent the last electron added to complete the electron configuration for a ground state atom of Br(Z = 35) according to the Aufbau principle, $n; l; m_{l}; m_{s}$

Options:

Answer:

Solution:

The valence shell configuration is $4 s^{2} 4 p^{5}$ and for the last electron $n = 4, l = 1$

$m = - 1, 0$ or $+ 1, s = + \frac{1}{2}$ or $- \frac{1}{2}$

Hence, $4, 1, 1, - \frac{1}{2}$
