Answer 2

Hey Mate Here is Ur answer :-

➡ . 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".

➡Lower electron orbitals fill before higher orbitals do, "building up" the electron shell.
