5. All the following isotopes undergo either alpha decay or beta decay. Predict whieh occurs for each. You can take the average atomic mass for each element as an indication of where the stable mass lies, and then judge whether the isotope's neutron/proton ratio ie l or too low, (This is not 100% reliable in general, but will do for this question.)
