Consider the following set of quantum numbers.

	$n$	$l$	${m}_{1}$
A	$3$	$3$	$-3$
B	$3$	$2$	$-2$
C	$2$	$1$	$+1$
D	$2$	$2$	$+2$

The number of correct sets of quantum numbers is

Solution

For a given ' $n$ ' value $l$ will have $0$ to $(n-1)$ values and for a given ' $l$ ' value $m$ will have $-m$ to $+m$ values

For $n=3,l=3,$ is not possible.Similarly for $n=2,l=2$ is also not possible, as $n$ and $l$ have same values.

So, set $A,D$ are not possible.

If $n=3,$ $l$ can have $0$ to $2$ values and ' $m$ ' can have $-2$ to $+2$ values,

So, set $B$ is possible.

If $n=2,'l'\mathrm{can}\mathrm{have}0\mathrm{and}1\mathrm{values}\mathrm{and}'m'\mathrm{can}\mathrm{have}-1\mathrm{to}+1\mathrm{values}.$

So, set C is also possible.

Hence, set $B$ and $C$ are the correct set of quantum nmbers.
