The primordial nuclide beryllium-9, the only stable beryllium isotope, is an example of this type of nuclide.
All odd mass numbers have only one beta decay stable nuclide.
There are about 355 known beta-decay stable nuclides total.
Alpha decay typically occurs in the heaviest nuclides.
However, as noted in the introduction, atomic weight and standard atomic weight represent terms for averages of isotopic abundances, not for single nuclides.
The most measured quantities in research on nuclear fission are the charge and mass fragments yields for uranium-235 and other fissile nuclides.
There is a build-up of radio nuclides.
Plutonium nuclides are so low as to be scarcely detectable.
