For part C, it asks how many electrons can have the following quantum numbers in an atom and it gives us n=4, l=2, ml= -2. The answer in the book is 2 electrons, can someone please walk me through it? Thank you.

Could someone actually go over the whole question? I'm not too clear on how to do this question.

This is a short clip explaining quantum numbers, hope it helps!!

a) 6
This is because when n=2, l=1 it's a p orbital and we know that p orbitals can hold 6 electrons

b) 2
It's 2 electrons b/c the numbers are describing each orbitals and each orbitals can hold 2 electrons

c) 8
When n = 2, it holds s + p orbitals
s can hold (2) and p can hold (6) = 8

d) 2
It's also 2 b/c the numbers are describing an orbital
Each orbital holds 2 electrons
Remember that ml is asking for the specific orbital in subshell
