During the lecture, Dr.Lavelle gave an example where n=2, l=1, and m=-1

From this, he told us this is an electron in 2px state. I don't exactly understand how he got the "x" from this information.

The quantum number m can be seen as in 3 axes, x, y and z. These axes correspond to the m numbers of -1, 0 ,1 used in the example. However, because the order can be flipped as 1,0,-1, professor Lavelle stated that the answer could be x or z.

The quantum number m refers to the can take values from l to -l, thus when m=-1 where l is equal to one, the electron is contained in the first subshell. Thus, it would be in the 2px subshell.

exactly what do all the quantum numbers represent?

i don't understand this either :/
