Maximum number of electrons in a subshell with $l=3$ and $n=4$ is
Maximum number of electrons in a subshell with $l=3$ and $n=4$ is
14
16
10
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
$\begin{aligned}
4 f \text { subshell } & =7 \times 2 \\
& =14
\end{aligned}$
