MCQ
What is the maximum numbers of electrons that can be associated with the following set of quantum numbers?

$n = 3, l = 1$ and $m = {-1}$

  • A
    $4$
  • ✓
    $2$
  • C
    $10$
  • D
    $6$
✓

Answer

Correct option: B.
$2$
b
The orbital of the electron having $=3, l=1$ and $m=-1$ is $3 p_{z}(\text { as } n / m)$ and an orbital can have a maximum of two electrons with opposite spins.

therefore, $3 \mathrm{p}_{z}$ orbital contains only two electrons or only $2$ electrons are associated with $\mathrm{n}=3, \mathrm{l}=1, \mathrm{m}=-1$
