1. What are the 4 part of Daltons Atomic theory.
2. Knowing Dalton atomic theory, what are two additional ways that you can state the Law of Conservation of Mass (beside mass is conserved).
a. __________________________________________
b. __________________________________________
3. What are the two results of Thomson's Expt. Please explain the results from what he did in the experiment.
4. What did Millikan, Goldstein and Chadwick contribute to the atomic theory and how did they do it. Be brief
5. What are the actual mass of the subatomic particles, location and charge.
6. Rutherford Gold leaf experiment is famous for determine the structure of the atom. Using the information from his experiment, explain how he got the characteristic of the thing he called "the nucleus".
7. What is the relative volume ratio (i.e. a graefuit vs. orange) of the volume of the nucleus compared to the volume of the overall atom?
8. What was Rutherford's shortcoming?
9. What are the two main part of Bohr's model of the atom.
10. Explain how Bohr said an atom used/interacted with energy?(CP or Level 2 DO NOT DO)
11. How is Bohr's energy level compared to the Periodic Table?(CP or Level 2 DO NOT DO)
12. What was the incorrect part of Bohr's understanding of the atom?
13. What did Planck and Debroglie say?(CP or Level 2 DO NOT DO)
14. What is a bright line spectrum, its significance with respect to the atom and what does a colored line on a bright spectrum mean?(CP or Level 2 DO NOT DO)
15. What are the wavelength of the color red and violet and what are the name of the region of the electromagnetic spectrum that have wavelength higher than red and lower that violet?(CP or Level 2 DO NOT DO)
16. Explain the Planck demonstration and how it relates to his equation? (2019-2020 Do not do) or (CP or Level 2 DO NOT DO)
Answer: Planck said that energy comes in discrete packets (called quanta) and the amount of energy in a packet of energy is directly related its frequency, E=hf.
17. A compound consists of 4.23g of H and 13.5g of C. If I have 26.8g of H, how many grams of gC do I have?
18. What is the frequency, wavelength and color of energy that is 4.63E-19J?(CP or Level 2 DO NOT DO)
