Electrons having same energy between same shell?

Postby David Sung 2H » Sun Oct 23, 2016 11:37 pm

On page 42 of the textbook it reads, "There are one 2s- and three 2p-orbitals in this shell; in hydrogen, they all have the same energy."

How come there is no energy difference between two different orbitals? Does this also apply to other elements or is it just hydrogen?

There is no difference in energy in the orbitals only for Hydrogen because there are no electron-electron interactions since the atom only has one electron. Many-electron atoms, however, are not degenerate (their orbitals have different energies to due interactions between electrons).
