Question #107704

What is the maximum number of electrons that can have the following set of quantum numbers? n=4, l= 3, ml= 1, ms= -1/2

Expert's answer

**exact orbital**, m_{l} = 1, in which the electrons reside. Since you know the exact orbital, it follows that only **two electrons** can share these three quantum numbers, one having spin-up, m_{s} = +1/2, and the other having spin-down, m_{s} = -1/2. And only one electron can share those four quantum numbers.
