Review Questions 2, 5, 7-10, 13-18, 27, 28 (p. 77)
Problems 31-36 (p. 78)

Class 5: After finishing our look at atomic symbols, we moved on to describing the electronic structure of an atom. That is, where do we expect to find an atom's electrons. Chap 3 sections 3.6-3.8
Review Questions: 11, 19-26, 34
