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.
