Q52 / 200 · NEET 2012 (Screening) · Chemistry

Maximum number of electrons in a subshell with $l=3$ and $n=4$ is

  • Correct answer
    A
    14
  • B
    16
  • C
    10
  • D
    12

Solution

$n$ represents the main energy level and $l$ represents the subshell. If $n=4$ and $l=3$, the subshell is $4 f$. In $f$ subshell, there are 7 orbitals and each orbital can accommodate a maximum of two electrons, so, maximum number of electrons in 4 $\begin{aligned} 4 f \text { subshell } & =7 \times 2 \\ & =14 \end{aligned}$

Hence, the correct answer is option: 'A'.
