Question

correct order of energies of atomic orbitals for hydrogen atom is​

Answer 1

Energy of Orbital in Hydrogen atom

Thus the energy of the orbitals in hydrogen atom increases as follows : 1s < 2s = 2p < 3s = 3p = 3d <4s = 4p = 4d = 4f <.. What are Degenerate orbitals Orbitals having the same energy are called degenerate orbitals.
