1. What quantum numbers specify these subshells?
5s: n=? l=?
5p: n=? l=?
3d: n=? l=?

You would do well to use the screen name. Changing keeps us from helping as much as possible.
Here are the rules.
n = 1,2,3.....in whole numbers.
l = 0,1,2,3, etc up to n1.
If l = 0 it i an s
if l = 1 it is a p
if l = 2 it is a d
if l = 3 it is a f.
So the first one is n = 5; l = 0
