Q3 Radium-224 decays through the pathway a, a, a, ß, a, ß. What intermediates are formed in this decay series? What is the final stable nucleus formed?
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. Figure Number of neutrons 110 100 90 80 70 60 50 40 30 20 10 0 0 www Belt of stability 10 1:1 neutron-to- proton ratio 20 30 40 50 60 70 80 Number of protons 1 of 1 "Magic" numbers A magic number is the name given to certain numbers of protons or neutrons that have a high correlation to stability in nuclei: magic numbers of protons: 2, 8, 20, 28, 50, 82 magic numbers of neutrons: 2, 8, 20, 28, 50, 82, 126, 184 ▼ A plot of the number of neutrons versus the number of protons for all known stable nuclei,…
