### Magnetic Quantum Number

Posted: Tue Oct 23, 2018 4:29 pm
I understand that for the p orbital, you can determine based off the magnetic quantum number if it is Px, Py, or Pz. But for the s, d, or f orbitals, are we supposed to be able to recognize which value of m lines up with which axis pairs?

I'm sorry if that wording made no sense.

Hi Sarah!

I believe we don't need to understand how each of the orbitals line up with the axes. S-orbitals are spheres, but d and f orbitals are very much complicated and are beyond the scope of our class.

Hope that helps!

I don't think we need to know the specific axis pairing. I think we just need to know that the d orbital has five different pairings

We mainly need to know the relationship between n, l, and ml in that ml is dependent on l, which is also dependent on n.
So, for example, knowing that n =3 and l=2, that means that ml could take on the values: -2,-1,0,+1,+2.
Hope this helps!

Can someone give me the the most simple definition of a wavefunction?

It's the function used to calculate the energy of an electron
