This is a Powerpoint lecture walking students through some of the major people, experiments, and milestones encountered as we learned more about the nature of matter. The history of the atom section covers Greek philosophers like Democritus, the atomic theory of John Dalton, and the experiments of Rutherford, Thompson, and Boyle. Finally, students will be shown the basics of the quantum mechanical model -- the current understanding of how protons, neutrons, and electrons work.

Essential Concepts: Atoms, alchemy, atomic theory, Law of Definite Proportions, Law of Multiple Proportions, plum-pudding model, planetary model, electron orbitals, quantum jumps, electron cloud model, principal energy levels, sublevels, magnetic quantum number, spin quantum number, electron orbital notation, Aufbau principle, Hund's Rule, Pauli Exclusion Principle.
