Midterm Review Q5 part f

5. f) How many electrons can have the quantum numbers n=3, l=1?

Why is the answer to this 6?

If l=1, this means that the possible ml values are 1, 0, and -1. Since there are 3 possible ml values, there are 3 different orbital states in which electrons can exist. Since 1 orbital can hold up to 2 electrons, 3 orbitals can hold up to 6 electrons.

Another way to think about it is by looking at the periodic table. n=3 corresponds to the 3rd row and l=1 corresponds to the p-block. Since there are 6 elements in one row of the p-block, the p subshell can hold 6 electrons.
