MCQ
Maximum electrons in a $d$-orbital are
  • A
    $2$
  • ✓
    $10$
  • C
    $6$
  • D
    $14$
✓

Answer

Correct option: B.
$10$
b
Maximum number of electrons held in the d orbitals is $10 .$

There are $5$ sub-levels in a $d$ orbital, each one can have a maximum $2$ electrons.

Hence, $5$ sub-levels can have a maximum of $10$ electrons.

Thus, $s, p, d$ and $f$ orbitals can accommodate a maximum of $2,6,10$ an $14$ electrons.
