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.

Write the nuclear equation for the radioactive decay of ^21-15P by positron emission. c.  Imagine that you started with a 0.1 g sample of iodine-131, and now you have only 0.025 g remaining. If the half-life of iodine-131 is 8 days, how old is the sample? Write 2 - 3 sentences explaining your reasoning. d. Draw a diagram that illustrates how nuclei change during nuclear fusion. Write 2 - 3 sentences describing the process of nuclear fusion, including where it occurs and how the energy released can be harnessed for use in homes.
