Question

What is the maximum number of electrons that can be associated with a following set of quantum numbers ? `(n = 3, l = 1 and m = -1)`.
A. 10
B. 6
C. 4
D. 2

Answer 1

Correct Answer - D
(D) The orbital of the electron having n=3, l=1 and m=-1 is `3p_(z)` (as `nl_(m)`) and an orbital can have a maximum number of two electrons with opposite spins.
`:. 3p_(z)` orbital contains only two electrons or only 2 electrons are associated with n=3, l=1, m=-1.
