Wikipedia Commons.4The Exclusion Principle (1924)All electrons have unique quantum number sets, so they cannot all fall to ground stateTwo-valuedness not describable classicallyAnother quantum number, later called spinElectrons could now be grouped into orbitals to explain their behaviorLed to Hunds rule and the Aufbau principle, essential to chemistrySwiss Federal Institute of TechnologyEidgenssische Technische Hochschule (ETH) in ZrichSucceeded Peter Debye as professor of theoretical physics in 1928
