Question

which are the possible values of $m_{ell}$ when $ell = 1,$? choose one: -1, 0, 1 -1/2, 1/2 0 -1, 1

Explanation:

Step1: Recall magnetic quantum number rule

The magnetic quantum number $m_{\ell}$ ranges from $-\ell$ to $\ell$ in integer steps.

Step2: Substitute $\ell = 1$

When $\ell = 1$, $m_{\ell}$ can take values $- 1,0,1$.

Answer:

-1,0,1
