7. A portion of the radioactive decay series that starts with Th-232 is as follows. For each step, write the product. Th-232 (goes through a decay) → ? (goes through ß decay) → ? (goes through B decay)? (goes through a decay) → ? (goes through a decay) → ? (goes through a decay) → ? 8. Two common units for measuring radioactivity are the Becquerel and the curie. Why are these names appropriate? 9. When 4.00 g of hydrogen nuclei fuse to form helium in the sun, 0.0265 g of matter is converted into energy. Using the mass converted to energy and the speed of light 3.00x 108 m/s and that a joule = kg m²/s², calculate how much energy is given off. =

Identification and Characterization of Unstable and Stable Nuclei Nuclear stability can in general be predicted based on the following considerations: • Nuclei with 84 protons or more are unstable. • Nuclei containing a magic number of protons and/or neutrons tend to be stable. • Stable nuclei often contain even numbers of protons and/or neutrons. These factors are reflected in the given graph (Figure 1). which shows the valley of stability as a function of number of neutrons and protons.
