The maximum number of electrons that can have principal quantum number n=3 and spin quantum number:
`m_(s)=-(1)/(2)` is

Text Solution

Verified by Experts

The correct Answer is:
9
Number of electrons `(n=3)=2n^(2)=18`. Half of these electrons will have anticlockwise spin, i.e., `m_(s) =-(1)/(2)`, i.e., 9 electrons.
