Question

question 8
how many orbitals are in the fourth electron shell, i.e., with ( n = 4 )?

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 \(n = 4\) into the formula

When \(n = 4\), we calculate \(n^{2}=4^{2}\).

$$4^{2}=4\times4 = 16$$

Answer:

16
