### Degeneracy

Can someone explain to me the concept of degeneracy? A friend tried explaining it to me but he made it seem more complicated. Also, I don't know if I am reading it right, but I don't understand what the textbook says.

### Re: Degeneracy

Degeneracy is basically the concept of orbitals being in the same energy level. For example, the 2px, 2py, and 2pz orbitals are all degenerate with each other because they all have the same energy level of n=2.

### Re: Degeneracy

Degeneracy is basically having the same value of n.
For example, if you were told to find the amount of degenerate orbitals in a 3p orbitals, there would be three different sets of quantum numbers you could use (because the spin of electrons doesn't matter in this situation):
-(3,1,-1)
-(3,1,0)
-(3,1,+1)

### Re: Degeneracy

Degenerate orbitals have the same energy levels. The degeneracy of orbitals is basically when they have the same values of n but different values of l. Hope this helps!

I believe that for elements with more than one electron, so basically every element except hydrogen, degeneracy is determined when the values for n and the values for l are the same.

### Re: Degeneracy

To find how many degenerate orbitals there are using Ml.
let's say L is 1.
so Ml is =-1,0,1
by that we count how many there are in Ml (3). so we have three degenerate orbitals for this atom.

### Re: Degeneracy

Degeneracy is orbitals with the same energy.

### Re: Degeneracy

Another thing to note is that when an atom only has one electron, the orbital energy only depends on the principle quantum number n. For example, in a hydrogen atom, a 2p orbital is degenerate with a 2s orbital.

However, this is not the case for multi electron atoms.

### Re: Degeneracy

Degeneracy is basically the levels of orbitals with the same energy, signified by the principle quantum number
