Question

in one atom, what is the maximum number of electrons that could have the quantum number of n = 4?

Explanation:

Step1: Recall electron - capacity formula

The formula for the number of electrons in a shell with principal quantum number $n$ is $2n^{2}$.

Step2: Substitute $n = 4$

Substitute $n = 4$ into the formula $2n^{2}$. So, $2\times4^{2}=2\times16 = 32$.

Answer:

32
