Our question says that we have an electron in the 4p sub -shell, and it says to list the n -l, m -s -o -l, and m -subs -s states available for an electron in this 4 -p sub -shell.
00:12
Okay, so because we're in the 4 -p sub -shell, we automatically are given the information by this fact of the value in, which is the principal quantum number.
00:25
And this is just the first number that shows up.
00:28
So it's 4p, so n is equal to 4.
00:31
The second number p gives us information about the orbital quantum number l, which characterizes the orbital angular momentum of the electron.
00:39
So if it was 4 sub s, then this would be l equals 0.
00:44
But 4 subp, the p represents l equal to 1.
00:47
So that information just comes right out of that 4p value.
00:51
So n equals 4 and l equals 1.
00:53
Okay, so then the next value that we would need is m sub l.
00:56
Well, m .s .bel is just the electron's orbital quantum number along the outer magnetic field, and it's an integer value, and it's equal to 0, plus or minus 1, plus or minus 2, all the way up to plus or minus l...
