### second quantum number

When discussing about the different blocks and the second quantum number, is the s-orbital only represented by l=0 regardless of what energy shell the electron is located in? For example, regardless if the electron is in the 2 or 4 shell, is the s-orbital always signified by l=0, p-orbital with l= 1, d-orbital with l=2, and f-orbital with l=3?

Yes the number matters here! The l = 0 always refers to the s-orbital, no matter what shell it's in. So l is always the same for each type of orbital.

Yes! Those l values will always correspond to their respective s, p, d or f subshells. The only thing that changes when you move up shells (ex. n=2 to n=4) is the possibility of subshells or l-values that work for that shell. For n=2, an electron can be in l=0 or 1 and for n=4, an electron can be in l=0,1,2 or 3.
