On a plot of number of neutrons as a function of number of protons, the stable (non-radioactive) isotopes form a "peninsula of stability". Isotopes with a greater or lesser number of neutrons than this, and all isotopes beyond a certain number of protons, are radioactive. Briefly describe the most common type of radioactive decay exhibited by each of these groups.
