Is degeneracy associated with a number? From what I understood, degenerate orbitals have the same energy level and become filled evenly. For example, when there are 3 2p orbitals in an atom, those orbitals all have the same energy level. s orbitals at different n levels, however, should have different energy levels and are thereby not degenerate, right?
The number of degenerate orbitals of an orbital is equal to twice angular momentum plus one (# degenerate orbitals = 2l + 1), so the s-orbital will have 1 degenerate orbital, the p-orbital will have 3, the d-orbital will have 5, and the f-orbital will have 7.
For an electron with quantum numbers n=3 and l=1, according to the formula (# of degenerate orbitals=2*l+1), the number of degenerate orbitals would be 2. However people have said that for a p orbital there are always 3 degenerates, so now I am confused. Is there any way to further explain this? In this case how many degenerate orbitals are there?
