Curie Notes 15: Orbitals and Electron Configurations
The electron is a wave that must fit around the nucleus. From that one idea come orbitals, four quantum numbers, and the address of every electron in every atom.
Learn orbitals, quantum numbers, the Aufbau, Pauli and Hund rules, and how to write electron configurations and box diagrams, with chromium and copper.
