### l numbers bigger than 3

What do l numbers bigger than 3 mean? I thought there were just s,p,d,f; but one of the problems is "what l numbers are possible for n=7" and the correct answer is anything 6 or less. What would an l number of 6 look like?

I think there are g, h, and i orbitals, there are just no elements with electrons at a ground state in any of those orbitals. The first element that has an electron that would occupy the g orbital would be element 121, which has not been discovered yet.

Hope this helps!

l can be any integer between 0 and n-1. So if n=6, then l can be anywhere between 0 and 5.

I'm pretty sure they're all theoretical; as in they don't technically exist (like there isn't a v-orbital that appears at n=5), but if you were able to have a n=7, then the l would theoretically be values [0,6]. Correct me if I'm wrong, though!

I am curious what would happen if a n= 5 was possible. That would be a new element, right?

n=5 does exist already, but the corresponding l values (such as l=4 which would be an g orbital) would be occupied by an element that has yet to be discovered. I think for any element to have an electron that occupies the l=4, you would need element 121, which has not been found yet.
