Section 6: Quantum Mechanical Model/Electron Cloud Model Read Describe the main difference regarding electron location in the Bohr model vs. the current Quantum Model. Electrons are in diffuse clouds Describe Werner Heisenberg’s Uncertainty Principle. How does this help explain current thoughts about electron location in the Quantum Model? You can never be sure of an electron’s location; only the probability of finding an electron. Electrons aren’t in hard, defined levels of location, but instead in a cloud. Section 7: Misc. Factoids (Chadwick) James Chadwick is credited with discovering which subatomic particle? Neutron Robert Millikan discovered something pretty important about the electron. View Video at What was his experiment called? Oil Drop Experiment What did he discover about the electron? Charge Timeline – use guide at Create a timeline with the following models: Dalton, Thomson, Rutherford, Bohr, and Quantum. Illustrate the models pictorially. You may draw or use the computer. Include: Names of discover and model name Picture of the Atom The year of discovery/release The significant difference between one model and the next
