Introduction to Radiation

An isotope is stable when it has a balanced number of neutrons and protons. In general, when an isotope is small and stable, it contains close to an equal number of protons and neutrons. Isotopes that are larger and stable have slightly more neutrons than protons. Examples of stable nuclides include carbon-12 (six

Where Do Chemical Elements Come From?

radioactive, while others are stable and never change. for example, nickel can appear in the form of 23 different isotopes. They all have 28 protons, but each isotope contains between 20 and 50 neutrons. Of these 23 isotopes, only five are stable, while the others are radioactive. If a nucleus produced through the “s”
