Lowest energy shell that contains f orbitals is the shell with n = 4.

Explanation:

Principle Quantum Numbers : It describes the size of the orbital and the energy level. It is represented by n. Where, n = 1,2,3,4

Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...

1. For f orbital, l= 3

For n,  l can have value 0 to (n-1).

For l=3, n has to be 4.

Thus the lowest energy shell that contains f orbitals is the shell with n = 4.
