2. What was J.J. Thomson's atomic model designed to explain? What was Ernest Rutherford's? 3. Why did Bohr find Rutherford's atomic model attractive? 4. Which spectrum can you identify an element from: continuous or discrete? 5. List the three fundamental principles of the Bohr model. 6. What was its main empirical testing ground? 7. What was Bohr's explanation for the discrete spectrum? 8. Why did the old quantum theory of atomic structure enter a state of crisis in the early 1920s? 9.
