The number of subshells associated with n = 4 and m = - 2 quantum numbers is:

Options

  1. A8
  2. B2
  3. C16
  4. D4

Correct answer

B. 2

Step-by-step solution

For n = 4 possible values of ℓ = 0 , 1 , 2 , 3 because values ℓ lie between 0   to   n - 1 We have to check values of m which lie between - ℓ   to + ℓ . ℓ = 2   &   ℓ = 3 can have m = - 2 So possible subshells are 2 .
