Predicting the decay mode Based on the valley of stability, the following processes generally tend to produce more stable neutron-to-proton (n/p) ratios: • Nuclei with Z284 tend to undergo a emission. • Nuclei with high n/p ratios undergo B(e) emission. • Heavy nuclei with low nip ratios are more likely to undergo electron (e) capture. • Light nucle with low nip ratios are more likely to undergo positron (e) emission. The classification "high" or "low" nip ratio can be determined by finding the coordinates on the graph that correspond to the number of protons (2 or horizontal value) and neutrons (or vertical value) in a given isotope. Then, observe whether this set of coordinates is above, within, or below the stability valley. Part B 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. ▸ View Available Hint(s) Reset Help iridium-104 thorium-232 lodine-137 calcium-50 fuorine-17 a decay Constants adecay emission capture
