Which of the following sets of quantum numbers is impossible arrangement?
Show Hint
$m$ ranges from $-l$ to $+l$, and $l$ ranges from $0$ to $n-1$.
Updated On: May 2, 2026
- $n = 3, m = -2, s = +\frac{1}{2}$
- $n = 4, m = 3, s = +\frac{1}{2}$
- $n = 5, m = 2, s = -\frac{1}{2}$
- $n = 3, m = -3, s = -\frac{1}{2}$

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
$m$ ranges from $-l$ to $+l$, and $l$ ranges from $0$ to $n-1$.
Step 2: Detailed Explanation:
For $n=3$, possible $m$ values are $-2,-1,0,1,2$. $m = -3$ is not possible.
Step 3: Final Answer:
The set with $n=3, m=-3$ is impossible.
