### quantum numbers

say for instance n=3
would l=0,1,2 and ml=-1,0,1? would that be it?

### Re: quantum numbers

Your values for l are correct but you don't have all the numbers for ml. ml = l, l-1, ..., -l. So basically for n=3, the values for ml would be -2, -1, 0, 1, and 2. You have to include the positive and negatives values for every number you stated for l.

### Re: quantum numbers

Since the possibilities for the quantum number l are 0, 1, and 2, we have to account for that in our consideration of the possible values for ml. Accounting for all the possibilities, there are a total of 9 possible orbitals: ml being 0 for l=0, ml being -1, 0, or 1 for l=1, and ml being -2, -2, 0, 1, or 2 for l=2, all of these possibilities within n=3.

For the ml values, you have to account for the negatives as well. For n=3, the ml values would be -2,-1,0,1,2.
