🤓 Based on our data, we think this question is relevant for Professor Tang's class at USF.

We are asked to identify the **lowest energy shell that contains an f orbital.**

To determine which quantum numbers will correspond an f** orbital**, let’s first define the values of first 2 quantum numbers:

**•**** principal quantum number (n) ****→**** **energy level in orbitals and its value could be **any positive integer** starting from 1

**•**** ****angular momentum quantum number (ℓ)**** ****→**** ****(l) has to be at least 1 less than n**, range of values from** 0 up to (n-1)**** **and each number corresponds to a subshell:

10. The lowest energy shell that contains f orbitals is the shell with n = __________.

A) 3

B) 2

C) 4

D) 1

E) 5
