(1986,1 M)
| $n$ | $l$ | $m$ | $s$ | |
|---|---|---|---|---|
| (a) | 3 | 2 | -2 | $\frac{1}{2}$ |
| (b) | 4 | 0 | 0 | $\frac{1}{2}$ |
| (c) | 3 | 2 | -3 | $\frac{1}{2}$ |

Answer:
Correct Answer: 39. (c)
Solution:
$ \begin{array}{llll} n & l & m & s \\ 3 & 2 & -3 & \frac{1}{2} \end{array} $
This is the wrong set of quantum number because $|m|$ cannot be greater than $l$.
