In an atom, the total number of electrons having quantum numbers
n = 4, $\left| m_{\mathcal{l}} \right| = 1$ and $m_{s} = - 1/2$ is

Show answer and solution

n = 4

m_{\mathcal{l}} = 1

Hence

\ \mathcal{l}

can be = 3,2,1
i.e. Hf; 2 orbitals
Hd; 2 orbitals
Hp; 2 orbitals
Hence total of 6 orbitals, and we want

ms\ = \ - \frac{1}{2}

, that
is only one kind of spin. So, 6 electrons.
