Hi there, in this question we have a true false question about the four quantum numbers.
00:06
So before we can answer this let's talk about what values these four quantum numbers can have.
00:11
N is of course the energy level, it describes the distance from the nucleus, and it can be any positive integer.
00:23
So the level closest to the nucleus with the least energy is n equals one, and then they increase in number as you move away from the nucleus.
00:33
So it can be any positive integer.
00:36
Our next quantum number l, l rather is the angular momentum quantum number, and that describes the subshell, the s, the p, the d, the f.
00:47
The values that it can be are integers that range from zero to n minus one.
01:01
So if n were four for example, l could be zero, one, two, or three.
01:06
M sub l, the magnetic quantum number, is also an integer, but it ranges from negative l to positive l.
01:22
So if l were three it could be negative three, negative two, negative one, zero, one, two, or three for example.
01:29
And then the spin quantum number, that describes the electron itself, that is limited to just one of two possible values, either positive one half or negative one half...
