degeneracy of the a 4p orbital

for question 5.c on test2:
how exactly should I answer: what is the degeneracy of a 4p orbital?

Re: degeneracy of the a 4p orbital

the degeneracy of a 4p orbital would be 3

Re: degeneracy of the a 4p orbital

The degeneracy would be 3 because there are 3 possible orientations for electrons in the p orbital.

Re: degeneracy of the a 4p orbital

I may be definitely wrong but I thought that degeneracy meant same energy level, do it would be 4s?

Re: degeneracy of the a 4p orbital

The degeneracy of a 4p orbital will be 3 because they all have the same energy level.

Re: degeneracy of the a 4p orbital

So we are not taking into account the spin of the electrons? I thought that the energy of an electron did not change if the electron had spin up or down. So for a 4p orbital, would we not have: n=4, l=1, m_l=1,0,-1 and m_s = +1/2,-1/2; a total degeneracy of 6?

Re: degeneracy of the a 4p orbital

All three p orbitals in a given shell are degenerate because they all have the same energy level.

Re: degeneracy of the a 4p orbital

Since it’s 4p, we know p has 1 subshell (l=1), that subshell has 3 orbitals and all those orbitals will have the same energy level

Re: degeneracy of the a 4p orbital

The answer would be 3 because p has one subshell, which will have 3 orbitals which all share the same energy level.

This would be the total number of electrons but degeneracy applies to orbitals with the same energy level not the number of electrons
