Name the Theory

100

states that a multi-electron atom is constructed occupying successive electrons in the lowest-energy orbital available.

Aufbau Prinzip

200

No two electrons on the same atom can possess the same four quantum numbers

Pauli Exclusion Principle

300

When populating electrons into a degenerate orbital set, electrons first occupy separate orbitals of the same degeneracy with spins oriented in the same direction

Hund's Rule

400

Atoms are hard spheres with no subatomic structure
