Question

Q2. Which of the following sets of quantum numbers is NOT permissible? And why? e, n = 2 , I = 1 , ml= underline 2 , ms = 1/2 d. n = 2 I = 1 , ml =1 , ms = - 1/2 c. n = 3 I = 3 ml =-3 ms = - 1/2 b. n = 4 I = 0 ml =0, ms = 1/2 a. n = 1 I = 0 ml =1 , ms = 1/2

Answer 1

Answer:

c

Explanation:

C is the correct answer because the value of l is from 0 to n-1 so in c, n=3 so l = 0 to (3-1) = 0 to 2 but here it is 3 which is not possible
