Quick question about Quantum Numbers

If "l" is 0 (i.e., if we're looking at the s-shell), what is the range for ml? Can it only be 0 as well?

ml= -l....0....+l

You can only have one quantum number for ml if l=0 which is in agreement with what we know about the s-subshell (only one orbital)

Yes so the only value for ml is 0. Why did you include -1 and 1? I believe that is inaccurate and would apply to an l value of 1.

Right, so it if l=0 then ml must equal 0? I'm basically asking if ml has to be 0 or 1 if l=0. I already know the ranges for all the other l values.

that's an L not the number 1

ml must be 0 if l=0

Perfect thanks.

And I think he brought up [-l, +l] range to signify what ml could be if we were not looking at the s-subshell, but rather p, d, or f.

For some reason I thought if l=0, then ml would equal 1. Just had to double-check. Thanks guys.

Sorry..they look alike :/

I was thinking the same thing as I was typing the response. I probably should of italicized it.

ml= -l...0...+l
