Question

Which of the following sets of quantum numbers is not allowed ?

Select the correct option:

$\mathrm{n}=3,1=2, \mathrm{~m}_i=0, \mathrm{~s}=+\frac{1}{2}$

$\mathrm{n}=3,1=2, \mathrm{~m}_k=-2, \mathrm{~s}=+\frac{1}{2}$

$\mathrm{n}=3,1=3, \mathrm{~m}_i=-3, \mathrm{~s}=-\frac{1}{2}$

$\mathrm{n}=3,1=0, \mathrm{~m}_i=0, \mathrm{~s}=-\frac{1}{2}$

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

$l = 0, 1, 2 \dots \dots (n - 1)$ $\therefore \text{for } n = 3$ $l = 0, 1, 2$ $\Rightarrow l = 3,$ $\text{not possible for } n = 3$
