For this question, we're given the orbitals 3p, 2f, or i'm sorry, i'm sorry, 4s, 2f, and 1p.
00:25
And we're asked which of these are incorrect designations.
00:30
So first, the first thing we're going to want to look at is the principal quantum number, n, and the orbital type l.
00:41
So n can be anywhere, any number from one above, but it has to be an integer.
00:48
L can be 0 to n minus 1.
00:55
L, however, also has letter designations.
01:00
So when we have 0, we have an s orbital.
01:04
When we have 1, we have a p orbital...
