What is the total number of orbitals in a principal energy level n = 3?
Understand the Problem
The question asks for the total number of orbitals in a principal energy level, specifically for n = 3. This involves understanding the relationship between the principal quantum number and the number of orbitals which can be calculated using the formula (n^2).
Answer
There are 9 orbitals in a principal energy level n = 3.
The total number of orbitals in a principal energy level n = 3 is 9.
Answer for screen readers
The total number of orbitals in a principal energy level n = 3 is 9.
More Information
In the n = 3 energy level, there are three subshells: 3s, 3p, and 3d. The 3s subshell contains 1 orbital, the 3p subshell contains 3 orbitals, and the 3d subshell contains 5 orbitals, adding up to 9 orbitals in total.
