the periodic table is organized according to the energy levels of the subshells. as additional electrons are required for each successive element, they are added to the lowest available orbital to \build\ the electronic configuration of the element. this procedure is known as the

domino effect

matrix principle

pauli exclusion principle

aufbau principle

Explanation:

The Aufbau principle states that electrons fill the lowest - energy orbitals first when building the electronic configuration of an element. The Domino effect is a non - relevant concept here. The Matrix principle is not related to electron filling. The Pauli exclusion principle states that no two electrons in an atom can have the same set of four quantum numbers, which is different from the described electron - filling process.

Answer:

D. Aufbau principle
