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, represented by reddish brown dots on the graph, shows that these nuclei cluster together in a region known as the valley of stability. Nuclei with a ratio that is too high tend to undergo beta decay. Nuclei with a ratio that is too low ten to undergo positron emission or electron capture.
Using general tendencies and the chart given in the introduction, predict the most likely mode of decay of each of the following radioactive isotopes. Drag the appropriate items to their respective bins.
Barium-150, sodium-26, americium, iridium-164, carbon-11
