[giffary]

Homework Statement

Find all possible values of L, Lz, and θ for an electron in a 3d state of hydrogen.


I confuse it long time..

explain me please..

 

[_Mayday_]

Do you not have any resource to work from or a textbook? Usually you have to offer some attempt at the solution.

 

[giffary]

the answer is

L = $$\sqrt{6h}$$

Lz = -2h, -h, h or 2h

but I don't know its solution.

Ask yourself, what do the 3 and d mean for a 3d state, what are the values of l and n for a 3d state of H?
