How many electrons in an atom could have these sets of quantum numbers?

Question

n=2
n=5, l=3
n=6, l=1, ml=-1

Answer 1

n = 2, the second shell can hole 8 electrons.

n = 5, l = 3. If l=0 that is an s electrons; if l = 2 that is a p electron and if l = 3 that is a d electrons. There can be 10 d electrons.

n = 6, l = 1, ml = -1. You try this one.
