Question: Which of the following is not permissible arrangement of electrons in an atom-
Options:
A) $ n=5,l=3,m=0,s=+,1\text{/}2 $
B) $ n=3,l=2,\text{ m}=-,3,s=-1/2 $
C) $ n=3,l=2,\text{ m}=-,2,s=-1/2 $
D) $ n=4,l=0,\text{ m}=0,s=-1/2 $
Show Answer
Answer:
Correct Answer: B
Solution:
- $ m=-l $ to $ +l $ , through zero thus for $ l=2 $ , values of m will be $ -2,-1,0,+1,+2. $ Therefore for $ l=2 $ , m cannot have the value -3.
