Lesson 1.1: Atomic models
Learning Goals: By the end of this lesson you will be able to
1. Describe atomic structure and theory, including key experiments;2. understand the basics of quantum mechanics, the wave model, quantum numbers, and electron configuration.
3. Define key terms: electron, radioactivity, nucleus, proton, neutron, isotopes, atomic number (Z), mass number (A), radioisotope, photoelectric effect, quantum, photon, spectroscopy, emission spectrum, continuous spectrum, line spectrum, transition, ground state.
Please read section 3.1 from Textbook pg134 - 141 to review on the early atomic theories and history of atomic model. The Powerpoint slides and video are also available for you to check out.
Focus on: Dalton's Billiard Ball model, J.J Thomson's Plum Pudding, Rutherford's model (Gold Foil Experiment), Bohr's model (orbit); Erwin' model (Quantum mechanical model).
Read textbook first, then watch this video for section 3.2.
- 1. Complete making a post on "Famous Experiment"
2. Self-study on Chapter 3.4 pg153 - 158, read sample problem 1 and 2 and work on pg159. #1, 3, 4, 5 - Please select one of the following experiment to record an ~2mins audio, explain how does the selected experiment work to make a discovery breakthrough.
1. Cathode ray tube - J.J Thomson
2. Millikan Oil droplet - Robert Millikan
3. Gold foil experiment - Ernest Rutherford
4. You could also fully talk about Planck's Quantum hypothesis
