Lecture - Basic Quantum MechanicsChemistry Quiz

What is the purpose of the Pauli exclusion principle, the aufbau principle, and Hund's rule in electron configurations?

• They predict the chemical properties of elements.

• They are used to write electron configurations.

• They determine the physical state of an element at room temperature.

• They are rules for naming chemical compounds.
