# Orbital angular momentum possible values of an electron in a hydrogen atom

## Homework Statement

What are the orbital angular momentum possible values for an electron in a hydrogen atom with a principal quantum number n = 3?

## Homework Equations

$L = \sqrt{l(l+1)}\hbar$

## The Attempt at a Solution

Possible values for l are 0, 1, 2.

So, substituting these in the equation above I get: 0, √2$\hbar$, √6$\hbar$.
