Which of the following is not permissible arrangement of electrons in an atom ?

Options

A. n=4, l=0, m=0, s=-1/2
B. n=5, l=3, m=0, s=+1/2
C. n=3, l=2, m=-3, s=-1/2
D. n=3, l=2, m=-2, s=-1/2

Answer

C

Explanation

(c) If n=3,
l=0 to (3-1)=0, 1, 2
m=-l to +l = -2, -1, 0 +1, +2
s=`+-(1)/(2)`
Therefore, option (c) is not a permissible set of quantum numbers.
