Answer 2

Explanation:

The Aufbau principle, simply put, means electrons are added to orbitals as protons are added to an atom. The term comes from the German word "aufbau", which means "built up" or "construction". The end result is that the atom, ion, or molecule forms the most stable electron configuration.
