Assigning Quantum Numbers

[vg19]

Hi,

What are the 4 quantum numbers for the last electron in the Al atom? I know how to get the primary quantum number and the spin quatum nmber, but I do not now how to get the secondary/azmuthal quantum number, and the magnetic quantum number.

The book gives the secondary/azmuthal quantum number as 1 "p", and the magnetic quantum number as -1

How do I get this values?

what shell is the last one in?

n = 3

what kindof shell

L = 1 (p shell)

what is the ml

since -L <= ml <= +L

and the negative one being the first subshell (px) and the positive one being the last subshell(pz)

and what is Ms?

Ms = +/- 1/2

where the positives are the first ones in and the negatives and the second ones in each of the subshells
