11. Lead-204 is entirely a primordial nuclide and is not a radiogenic nuclide . 12. Being a primordial nuclide , Helium-3 is not naturally produced on earth. 13. The daughter nuclide of an alpha decay is an isodiapher of the original nucleus. 14. In all of the above examples, the initial nuclide decays into only one product. 15. For example, 14 C or 18 F . You may use a nuclide template. 16. In the following decades, the Karlsruhe Nuclide Chart was published and revised several times. 17. Argon-36 is presently the lightest known " stable " nuclide which is theoretically unstable. 18. In many cases members of the decay chain are far more radioactive than the original nuclide . 19. The word " nuclide " was proposed by Truman P . Kohman in 1947. 20. See stable isotope and primordial nuclide .
