A handout designed to go along with the atomic theory video at ChemistryIsMyJam.com. The video covers the key experiments that changed the model of the atom over time. This includes a brief overview of Democritus, John Dalton, JJ Thomson, Neils Bohr, Ernest Rutherford, Erwin Schrodinger, and Werner Heisenberg. The models of the atom discussed are the Plum Pudding Model, the Planetary Model, and the Quantum Mechanical Model. This is a resource designed to help teachers flip their chemistry classroom.
