JEE PYQ: Atomic Structure Question 16
Question 16 - 2020 (02 Sep Shift 2)
The number of subshells associated with $n = 4$ and $m = -2$ quantum numbers is:
(1). (8)
(2). (2)
(3). (16)
(4). (4)
Show Answer
Answer: (2)
Solution
For $n = 4$, only $\ell = 2$ and $\ell = 3$ can have $m = -2$. So 2 subshells.
