MCQ
The maximum number of electrons that can be filled into all the orbitals corresponding to the azimuthal quantum number $l = 3,$ is :
  • $14$
  • B
    $15$
  • C
    $12$
  • D
    $18$

Answer

Correct option: A.
$14$
For $l = 3,$ possible values of $m = 2l + 1 = 7$. For each m, there can be $2$ electrons filled.
Maximum number of electrons, thus $= 2 \times 7 = 14.$
