Consider an electron in the state n=4, l=3, m=2, s=1/2.

In what shell is this electron located?

-I put 4 but it said it was wrong.

What is the orbital angular momentum L of this electron in h(bar)s?

What is the z component of the orbital angular momentum of this electron, Lz?

What is the z component of the spin angular momentum of this electron, Sz?

**Update:**
If L is sqrt(12) h then it should be 3.46 * 6.6*10^-34. I’m getting 2.29*10^-33 and it’s saying I’m wrong.

**Update 2:**
Nevermind. The answer is the square root of 12.
