# Defining quantum numbers for orbital states? watch

1. The 2p orbitals for hydrogen atom have the functional form:
1) Ψ(p, θ, Φ) = sin(θ)e^iΦpe^-p/2

Quantum numbers:

n= 2 because it's a 2p orbital
l = 1

ml ? I know the magnetic quantum number is associated with the z-component of the orbital angular momentum.
but when I apply it, I'm not too sure how to differentiate it?
It should be 1 because e does contain Φ?

spans from to in integer steps, so it'll depend on which 2p orbital you're talking about.

Oh yeahhhhh
so, how would I do it?

Well one of the 2p orbitals will have , one will have , etc. (it's a bit more complicated than this though see: https://chemistry.stackexchange.com/...eal-p-orbitals, the x and y states are considered to be linear combinations of the x and y 'orbitals' due to their degeneracy in the xy plane)
