1) Describe the Rutherford alpha scattering experiment. What did he and his students observe, and what conclusions did they give? What is the impact of Rutherford’s conclusions on the structures of atoms? 2) Both the hertz and the curie have dimensions of s-1. Explain the difference between these two units. 3) Explain the SI errors (if any) in and give the correct equivalent units for the following units: (a) m-grams/pL, (b) megaohms/nm, (c) Bq/milli-Curie. 4) Assuming that a nucleus is a sphere of nuclear matter of radius 1.2 x A1/ 3 fm, express the average nuclear density in SI units. 5) By inspecting the chart of the nuclides, determine which element has the most stable isotopes? 6) How many neutrons and protons are there in each of the following nuclides: (a) 10B. (b) 24Na, (c) 59Co. 7) Is the reaction N + 4He 14 17 O + 1H endothermic or exothermic? How much energy is absorbed or released in the reaction? Masses: H, 1.007825; n, 1.008665; He, 4.00260; 14 N, 14.00307; and 17O, 16.99914. 8) What are nuclear reactions and how are they different from chemical and physical reactions? Give two examples of nuclear reactions and explain how the products can be identified.
