Question

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

• A. 4
• B. 8
• C. 2
• D. 16

Answer 1

Answer: (C)

n = 4
For n=4, the possible 'l' values are 0,1,2,3.
l = 0 m = 0
l = 1 m = -1, 0, +1
l = 2 m = -2, +2, -1, +1, 0
l = 3 m = $\pm 3,\pm 2,\pm 1,0$
Answer: '2' Subshells
