All right, so we have the principal quantum numbers, which correspond to the energy levels, n equals 1, we have n equals 2, n equals 3, and n equals 4.
00:11
Within each one, we'll have n subshells.
00:14
So for n equals 1, there will be one sub shell.
00:17
And the value is an integer starting with 0, up to 1 less than n.
00:22
So if n equals 1, we start with 0.
00:24
So the l, the sub level, can be equal to 0, and that's it because you can't go to 1.
00:29
And then for n equals 2, you'll have two subshells, 0 and 1, and then you can't have 2.
00:36
And then for 3, n equals 3, l equals 0, 1, or 2, and if n equals 4, l equals 0, 1, 2, or 3.
00:45
This gives you the number of subshells.
00:50
And then the orbitals, so if l equals 0, then we have an m sub -l, which corresponds to the orbital orientation, and that is just going to be zero.
01:01
There's going to be one of them.
01:02
Then if l equals 0, we'll have m subl equals 0.
01:08
If l equals 1, we have m sub l equals negative 1, 0, or 1...
