This Chemistry lesson is titled Discovery of the Nucleus Rutherfords Gold Foil Experiment and will give a detailed explanation of the topic.

Craig Beals explains why some atoms emit radiation through the processes of radioactivity and radioactive decay. He examines the role of isotopes in radiation and shows Uranium - 238 from Carnotite Ore and Americium - 241 from a smoke detector.
