# 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?

Nov 5, 2016

Possible values for ${m}_{l} = - 2 , - 1 , 0 , + 1 , + 2.$

#### Explanation:

Principal quantum number $\left(n\right) =$ 3. [Given].
Angular momentum quantum number $\left(l\right) = 2.$ [Given].

So, Magnetic Quantum numbers $\left({m}_{l}\right)$ lies from $- l$ to $+ l$ through $0.$

$\therefore$ Possible values for ${m}_{l} = - 2 , - 1 , 0 , + 1 , + 2.$
