Which of the following is an incorrect set of quantum members?

Options

  1. An = 2 ,   l = 0 ,   m = 0
  2. Bn = 1 ,   l = 0 ,   m = 0
  3. Cn = 3 ,   l = 3 ,   m = 0
  4. Dn = 2 ,   l = 1 ,   m = 1

Correct answer

C. n = 3 ,   l = 3 ,   m = 0

Step-by-step solution

Maximum l value should be equal to n−1 and it cannot be equal to n. ∵ for ( l ) It can be upto ( n - 1 ) and Thus, m = ± l i.e. + l , 0 , - l for (a) n = 2 , l = 0 , m = 0 (correct), for (b) n = 1 , l = 0 , m = 0 (correct), (c) n = 3 , l = 3 (not correct), (d) n = 2 , l = 1 , m = 1 (correct),
