Let's look at the electron configuration for the quantum state where n is equal to 2.
00:16
I'm sorry, 3.
00:19
So the quantum state where n equals 3, l is equal to 2, and then our m subl is going to equal negative 2.
00:32
So now for the state that we're in, n equals 3, l equals 2, there are our m subl is going to equal negative 2.
00:37
Five different geometries that this could take because of each of these.
00:44
Now remember your ml number can be from negative to positive your l number.
00:49
So that means for mls in this state you could have it at negative two, negative one, zero, one, and two.
01:02
So five different ways that this could get configured within this state.
01:06
But we are only interested in this one here.
01:12
So the ml equals negative 2.
01:15
Now as long as you're not on the 0, you get a four balloon shape of probability...
