1. The problem statement, all variables and given/known data

From past paper:

State the selection rules for (electric) quantum numbers n,l,m,s and j.

2. Relevant equations



3. The attempt at a solution

My problem is that looking online, there seems to be an m(s) and m(l). Is the question assuming that I state the selectrion rules for both?

In my lecture notes though, in one of the summaries, it says "delta(m)=0,plusminus1" for selection rules.

The m(s) and m(l) thing has been bugging me a lot lately infact.
