Do these inconsistencies mean that Dalton was wrong? Is Dalton's model still useful? Explain. 2.31 Use Dalton's theory to explain why potassium nitrate from India or Italy has the same mass percents of K, N, and O. The Observations That Led to the Nuclear Atom Model Concept Review Questions 2.32 Thomson was able to determine the mass/charge ratio of the electron but not its mass. How did Millikan's experiment allow determination of the electron's mass? 2.33 The following charges on individual oil droplets were obtained during an experiment similar to Millikan's: -3.204x10-19 C; -4.806x10-19 C; -8.010×10¬19 C; -1.442x1018 C. Determine a charge for the electron (in C, coulombs), and explain your anşwer. 2.34 Describe Thomson's model of the atom. How might it ac- count for the production of cathode rays? 2.35 When Rutherford's coworkers bombarded gold foil with a particles, they obtained results that overturned the existing (Thomson) model of the atom. Explain. The Atomic Theory Today (Sample Problems 2.4 and 2.5)
