Which of the following sets of quantum numbers is not possible?

View answer and explanation

Correct option: D

n=4, l=1, m=+2, s=-\frac{1}{2}

Option D (

n=4, l=1, m=+2, s=-\frac{1}{2}

) is correct because the value of the magnetic quantum number (

m

) must be within the range of

-l

to

+l

, and when

l=1

,

m

can only be -1, 0, or +1.
