1. Thomson himself was perhaps the biggest critic of the model referred to as "plum pudding." He tried for years to make it work. What experimental data could he not predict? Why couldn't he make the planetary model of Rutherford-Bohr work?
2. Does it seem fortuitous that most of the successful physicists who helped unravel the secrets of atomic structure (Thomson, Rutherford, Bohr, Geiger, and Moseley) worked either together or in close proximity in England? Why do you suppose we don't hear names of physicists working on this idea in other European countries or in the United States?
3. Could the Rutherford scattering of a particles past 90° be due to scattering from electrons collected to- gether (say, 100 e-) in one place over a volume of diameter 10-15 m? Explain.
