Q. Which of the following is not possible?
A) $n = 2,\ l = 1,\ m = 0$
B) $n = 2,\ l = 0,\ m = - 1$
C) $n = 3,\ l = 0,\ m = 0$
D) $n = 3,\ l = 1,\ m = - 1$
Explanation
(b)
$n = 2,\ l = 1,\ m = 0$ it is possible
$n = 2,\ l = 0,\ m = - 1$ it is not possible because if $l - 0,\ m$ must be 0. The value of $m$ totally depends upon the value of $l(m = - l\ to + l).$
$n = 3,\ l = 0,\ m = - 0$ it is possible.
$n = 3,\ l = 1,\ m = - 1$ it is possible.
