Hi.
00:01
So in this case, we're given a different set of orbital diagrams for the orbital.
00:07
So in this case, in all of the cases, we're going to have like five boxes.
00:12
So i'm going to write down first all of the configurations that are given to you.
00:17
That are a total of five configurations.
00:21
And then we're going to see which ones are possible.
00:28
So the first one, we have two electrons up and down.
00:35
Then we have two electrons looking up.
00:40
And all of these guys are looking up.
00:42
So first of all, this first configuration cannot be possible by following the half -bow rules for filling orbitals.
00:50
Because we know that when we fill an extra electron into one orbital, it needs to have an anti -parallel spin.
00:57
That means that if you have an arrow up, then the next electron is going to enter as an arrow down.
01:03
So for this first configuration, we have that case.
01:07
For the second one, for us, we're going to have the same scenario.
01:15
So in this case, because of these pair of electrons that are both alpha electrons, this is not going to be a possible configuration or the correct arrangement.
01:28
So next up, we're going to have all of the orbitals are going to be filled...
