Well, I suppose it would be the following...
Two common mistakes would be:
- Not knowing which orbitals physically exist AND why they do not.
- Forgetting the difference between orbitals and subshells.
So, consider the following examples.
-
Recall that the principal quantum number
n = 1, 2, 3, . . . and the angular momentum quantum numberl = 0, 1, 2, . . . , ul(n-1) .Therefore, it follows that if
n is some integer, thenl can be no greater thann , i.e.1p ,2d , and3f orbitals do not exist, etc. because for these, it is NOT the case thatl < n , while it must be. -
Or, we distinguish between the fact that if you have a set of
d orbitals, it does not mean that10 electrons can go into one orbital...But it DOES mean that you can have
10 electrons total in that subshell, as there can be2 electrons perd orbital, of which there are5 .
