The pattern of systematically building up the electron configurations for the elements is known as ________.
A) Coulomb's law
B) the Pauli exclusion principle
C) Hund's rule
D) the aufbau principle

Question

Quizplus · Accepted Answer

The aufbau principle is the systematic method of building up the electron configurations for the elements based on the order of increasing atomic number. Coulomb's law describes the attraction between two charged particles, Pauli exclusion principle states that no two electrons in an atom can have the same set of four quantum numbers, and Hund's rule dictates that electrons fill orbitals singularly first before pairing up. While these principles are important in understanding electron configurations, they do not describe the systematic building up of the configurations.
