Question

Which combinations of quantum number n , $l$ ,m, s, for the electron in an atom does not provide a permissible solution of the wave equation?

• A. 3, 2, -2, 1/2
• B. 3, 3, 1, -1/2
• C. 3, 2, 1, 1/2
• D. 3, 1, 1, -1/2

Answer 1

Answer: (B)

3, 3, 1, -1/2

As we know,
n = 1, 2, 3...............
$l$ = 0 to n-1
m = $-l$ to $+l$
s = +1/2 and -1/2
From here we can see that, 3, 3, 1, -1/2 is not possible as $n=l$ is not possible.
