what rule/ principle states that electrons fill orbitals from lowest energy to highest energy?\naufbau principle\nhunds rule\npauli exclusion principle

Answer

Brief Explanations:

The Aufbau principle states electrons fill orbitals starting from the lowest - energy ones and moving to higher - energy ones. Hund's rule is about the maximum number of unpaired electrons in degenerate orbitals. The Pauli exclusion principle states that no two electrons in an atom can have the same set of four quantum numbers.

Answer:

A. Aufbau principle
