Q. Which combinations of quantum numbers $n,\ l,\ m\ and\ s$ for the electron in an atom does not provide a permissible solution of the wave equation?
A) $3,\ 2,\ 1,\ \frac{1}{2}$
B) $3,\ 1,\ 1,\ - \frac{1}{2}$
C) $3,\ 3,\ 1,\ - \frac{1}{2}$
D) $3,\ 2,\ - 2,\ \frac{1}{2}$
Explanation
(c)
When $n = 3$, number of values of $l\ are\ 0$ to $(n - 1)i.e.,$ 0, 1, 2
Hence,
when $n = 3,\ then\ l = 3\ does\ not\ exist.$
