Hi there.
00:03
In this question, we have the five orbitals of 3d.
00:10
So the five 3d orbitals.
00:12
I'm just representing them with a line.
00:15
And it looks like we have three electrons to place in here.
00:19
So we know when we are placing electrons into orbitals that have the same energy, huns rule says that one electron needs to go into each orbital before you double up.
00:36
So huns rule says one electron.
00:41
In each orbital of equal energy before we double up.
01:05
Okay, you can kind of think of it like they prefer to live in these small houses alone, if they can, before they accept a roommate.
01:18
All right, so the three electrons, they're going to have the same spin...
