Right so it says how many electrons can have the following quantum numbers so n is four l is um l is two m subscript l is what minus two and m subscript s is plus half okay so let's get it so so we're talking about the 4, 2 means that is the d, right? basically, that is the d subshell, right? and of course, the 4d election.
00:38
So it's a 4d election, basically.
00:41
It's a 4d election.
00:42
And in the 4d, the d subshell, there are five orbitals.
00:46
You have 1, 2, 3, 4, 1, 2, 3, 4, 5, right? and when this is each of them, the ml value, this is minus 2, minus 1, 0, 1, and 2.
01:01
And so you can have two electrons, a maximum of two electrons in.
01:06
And of course, it says plus half...
