Question

What are the possible values for `m_l` when the principal quantum number (n) is 3 and the angular momentum quantum number (`l`) is 2?

Answer 1

Possible values for `m_l = -2,-1,0,+1,+2.`

Explanation:

Principal quantum number `(n)=` 3. [Given].
Angular momentum quantum number `(l)=2.` [Given].

So, Magnetic Quantum numbers `(m_l)` lies from `-l` to `+l` through `0.`

`:.` Possible values for `m_l=-2,-1,0,+1,+2.`
