# How many orbitals are in the n=3 level?

**Answer:** The n=3 level has 9 orbitals.

**Explanation:** In the context of the electron configuration, 𝑛 represents the principal quantum number, which indicates the energy level or shell of an electron.

The number of orbitals in a given energy level is determined by the value of 𝑛. For 𝑛=3, there are 3 subshells (s, p, and d), each with a maximum number of orbitals as follows:

- 1 s orbital in the 𝑛=3 level (s subshell)
- 3 p orbitals in the 𝑛=3 level (p subshell)
- 5 d orbitals in the 𝑛=3 level (d subshell)

Adding up the orbitals from each subshell gives a total of 9 orbitals in the 𝑛=3 level.
