Why and how are orbitals said to be degenerate? I'm reading Housecroft's Inorganic Chemistry and I don't know how I've missed it but I have a feeling this is of some importance later on.
My understanding is that the electron's probability of being in a position degenerates with increasing distance from the nucleus, is this what degenerate orbitals are?
Then comes orbitals that are not degenerate such He, now I am a little confused. Would someone be kind to lead me with their rationale to an understanding of degenerate and non-degenerate orbitals?
