JJ Thomson and the Plum Pudding Model

We have discussed the work of JJ Thomson in studying cathode ray tubes.  Based upon his findings, Thomson put forth a model of the structure of an atom which included charged particles.

HW: Journal entries: (1) Summarize the Sticky Tape Lab; (2) Explain the discovery of the electron (cathode rays) and JJ Thomson’s model of the atom – describe the behavior of electrons.
