Hi! Can someone please explain degeneracy of electrons?

As I discussed in class. Degeneracy means same energy.

Degeneracy of orbitals means that there are no electrons in the orbitals at ground state and as a result, have the same energy as other orbitals in the energy level. For example, hydrogen has degenerate orbitals for everything higher energy than the 1s, meaning that its orbitals in energy level 2 all have the same energy (orbitals in 2s and 2p both have the same energy).

Degenrate simply means same energy. With Hydrogen, all orbitals of the shell have the same energy, even if the orbital angular momentum value is different.

do you have any other examples that might make it a bit more clear? thanks so much.

Any element with 1 electron (such as Hydrogen or ions with one electron Li2+) would have degenerate orbitals (meaning that the orbitals in a given shell have the same energy).

"electron orbitals that have the same energy levels are called degenerate orbitals. ... For example, p orbitals consist of three degenerate orbitals that all have exactly the same energy level."

Degeneracy indicates that the orbital has the same energy. For instance, 3px and 3py are degenerate orbitals because they have the same amount of energy.

Degeneracy simply means same energy; it is indicating that the orbitals within that shell have the same energy.

It means having orbitals that are in the same energy level. So for the s-orbital it would be 1, p would be 3 and so on.

Would the degeneracy be the same as the quantum number l then?

No if two atoms have the same n value, then they share degeneracy. The l value is the subshell that the electron is located.
