MCQ
Which of the following is not permissible arrangement of electrons in an atom
  • A
    $n = 3\, ;\, l = 2\, ;\, m = -2\, ;\, s =  - \frac{1}{2}$
  • B
    $n = 4\, ;\, l = 0\, ;\, m = 0\, ;\, s =  - \frac{1}{2}$
  • C
    $n = 5\, ;\, l = 3\, ;\, m = 0\, ;\, s =  + \frac{1}{2}$
  • ✓
    $n = 3\, ;\, l = 2\, ;\, m = -3\, ;\, s =  - \frac{1}{2}$
✓

Answer

Correct option: D.
$n = 3\, ;\, l = 2\, ;\, m = -3\, ;\, s =  - \frac{1}{2}$
d
when $l = 2$ then
possible value of $m$ is
$-l$ to $+l$
so $m = -3$ is not possible
