What is the lowest energy level having f orbitals?

Understand the Problem

The question is asking about the energy levels in atomic structure, specifically identifying the lowest energy level that includes f orbitals. This involves understanding the quantum mechanical model of electrons in atoms and the arrangement of orbitals.

More Information

The f orbitals are more complex and start appearing in the fourth energy level (n=4), which includes the 4f sublevel.
