how many orbitals does the n = 4 shell have?

how many orbitals does the n = 4 shell have?
Answer
Explanation:
Step1: Recall the formula for number of orbitals
The number of orbitals in a shell with principal - quantum number $n$ is given by $n^{2}$.
Step2: Substitute the value of $n$
Here, $n = 4$. So, the number of orbitals is $n^{2}=4^{2}=16$.
Answer:
16
