Q. Which of the following sets of quantum numbers is not allowed?
JEE Main
JEE Main 2022
Structure of Atom
A
$n =3,1=2, m _{ l }=0, s =+\frac{1}{2}$
13%
B
$n =3,1=2, m _1=-2, s =+\frac{1}{2}$
6%
C
$n =3,1=3, m _{ l }=-3, s =-\frac{1}{2}$
67%
D
$n =3,1=0, m _1=0, s =-\frac{1}{2}$
13%
Solution:
$ 1=0,1,2 \ldots \ldots(n-1) $
$\therefore \text { for } n =3 $
$1=0,1,2$
$ \Rightarrow 1=3 $
not possible for $n =3$
