The Band of Stability
... Introduction: Radioactivity is the spontaneous emission of radiation by nuclei. Radioactive decay changes the nature and identity of an atom’s nucleus. This occurs for a specific reason. Elements from hydrogen to lead (atomic numbers 1-82) have stable isotopes in which the tendency of protons to rep ...

Ch.7 Summary Notes
... When some nuclei undergo fission, they release subatomic particles that trigger more fission reactions. This ongoing process in which one reaction initiates the next reaction is called a chain reaction. The number of fissions and the amount of energy released can increase rapidly and lead to a viole ...
