Orbitals in an H-Atom

Postby Sarah Zhari 1D » Thu Oct 17, 2019 11:10 pm

In the textbook, it states that in a hydrogen atom, "all the orbitals of a given shell are degenerate (have the same energy)". Why do all the orbitals in a hydrogen atom have the same energy?

Hydrogen atoms only have one electron in an s-orbital, so there is not really any electron-to-electron repulsion occurring to differentiate between the different s, p, d, and f orbitals. In atoms with multiple electrons, the interaction between the electrons causes variations in angular components and spatial extents, causing them to have differing energies.

Hydrogen only has one electron, I think it's the interactions between electrons that cause these differences in energy levels.

In lecture he said it's helpful to think of orbitals as functions opposed to a tangible path. So because H atoms only have one electron in an s orbital there would be no difference in energy levels and therefore only one orbital
