Question
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.
