12. what is the maximum number of electrons that can fit in 3p? 4f?

Question

Accepted Answer

# Explanation:
## Step1: Recall electron subshell rules
The maximum number of electrons in a subshell is given by the formula $2(2l + 1)$, where $l$ is the azimuthal quantum number. For a $p$-subshell, $l = 1$; for an $f$-subshell, $l = 3$.

## Step2: Calculate for 3p subshell
For $3p$ ( $l = 1$ ):
$$
\begin{align*}
2(2l + 1)&= 2(2\times1 + 1)\
&= 2(3)\
&= 6
\end{align*}
$$

## Step3: Calculate for 4f subshell
For $4f$ ( $l = 3$ ):
$$
\begin{align*}
2(2l + 1)&= 2(2\times3 + 1)\
&= 2(7)\
&= 14
\end{align*}
$$

# Answer:
The maximum number of electrons in $3p$ is 6, and in $4f$ is 14.
