Primordial nuclide The shortest-lived primordial nuclides (i.e. nuclides with shortest half-lives) are:
List of elements by stability of isotopes Additionally, about 29 nuclides of the naturally occurring elements have unstable isotopes with a half-life larger than the age of the Solar System (~10 years or more). An additional six nuclides have half-lives longer than 100 million years, which is far less than the age of the solar system, but long enough for some of them to have survived. These 32 radioactive naturally occurring nuclides comprise the "radioactive" primordial nuclides. The total number of primordial nuclides is then 254 (the stable nuclides) "plus" the 32 radioactive primordial nuclides, for a "total" of 286 primordial nuclides. This number is subject to change if new shorter-lived primordials are identified on Earth.
Nucleogenic Because nucleogenic isotopes have been produced later than the birth of the solar system (and the nucleosynthetic events that preceded it), nucleogenic isotopes, by definition, are not primordial nuclides. However, nucleogenic isotopes should not be confused with much more common radiogenic nuclides that are also younger than primordial nuclides, but which arise as simple daughter isotopes from radioactive decay. Nucleogenic isotopes, as noted, are the result of a more complicated nuclear reaction, although such reactions may begin with a radioactive decay event.
Primordial nuclide All of the known 254 stable nuclides occur as primordial nuclides, plus another 32 nuclides that have half-lives long enough to have survived from the formation of the Earth. These 32 primordial radionuclides represent isotopes of 27 separate elements.
Isotopes of indium Indium (In) consists of two primordial nuclides, with the most common (~ 95.7%) nuclide (In) being measurably though weakly radioactive. Its spin-forbidden decay has a half life of 441 trillion years.
