### Degeneracy

what does degeneracy mean and how do we determine it for orbitals?

Also when do we use orbital, shell, and subshell, I find myself using these words interchangeably.

Degeneracy basically means of which orbital.bThe degeneracy of s=1, p=3, d=5, f=7
Think of it this way: Shell is n, subshell is l (in those subshells are "orbitals")

All electrons that have the same value for n are in the same shell.
Within a shell (same n), all electrons that share the same l (the angular momentum quantum number, or orbital shape) are in the same sub-shell
When electrons share the same n, l, and ml, we say they are in the same orbital (they have the same energy level, shape, and orientation).
I think essentially degeneracy means the number or orbitals, or ml (s has 1; p has 3; d has 5; f has 7) because that's what I put on my test and it was correct.

To calculate the number of degenerate orbitals, you can use 2l + 1.

### Re: Degeneracy

Degeneracy corresponds with the orbitals, therefore; they go as follows, s=1, p=3, d=5, f=7.

Degeneration refers to all the orbitals having the same energy. For example, the three orbitals in 3p are considered degenerate because they have the same energy. Hope this helps.

### Re: Degeneracy

Degenerate orbitals are orbitals with the same energy. This degeneracy can sometimes be "lifted" by external electric or magnetic fields.
