Okay, we're asked to do the following.
00:02
For fundamental quantum number n equals 4, show the locations by calculating the quantum number of the shell, subshell, orbital, and spin.
00:13
You can show by drawing boxes.
00:17
So for 4, not sure exactly what they mean here.
00:23
For 4, for n equals 4, n has to be, let's go n, l, m, l, and m, s.
00:42
So of course, m for each of these has to be 4.
00:44
L can be either 0, 1, 2, or 3.
00:52
It can be any one of those.
00:54
If it's 0, this can be 0.
00:59
This can be plus 1 half or minus 1 half.
01:04
Those are my options for if it's in the s sub level.
01:07
Here it's minus, oops, minus 1, 0, and plus 1.
01:14
Here it's minus 2, minus 1, 0, plus 1, plus 2.
01:20
And here it's minus 3, minus 2, minus 1, 0, plus 1, plus 2, plus 3.
01:31
Those are all the possibilities.
01:33
All of these are plus 1 half and minus 1 half.
01:49
Show the locations by calculating them according to the quantum number of the shell, the subshell, the orbital, and spin...
