what rule/principle states that electrons fill orbitals from lowest energy to highest energy?\naufbau principle\nhund’s rule\npauli exclusion principle
Answer
Answer:
A. Aufbau principle
Brief Explanation:
The Aufbau principle dictates that electrons fill atomic orbitals starting from the lowest - energy orbitals and moving to higher - energy ones. Hund's rule is about maximizing parallel spins in degenerate orbitals, and the Pauli exclusion principle states that no two electrons in an atom can have the same set of four quantum numbers.
