Of elements whose most stable isotopes have been identified with certainty, francium is the most unstable. All elements with atomic number of 106 ( seaborgium ) or greater have most-stable-known isotopes shorter than that of francium, but as those elements have only a relatively small number of isotopes discovered, the possibility remains that ...
Francium-223 is the most stable isotope, with a half-life of 21.8 minutes, [8] and it is highly unlikely that an isotope of francium with a longer half-life will ever be discovered or synthesized. [22] Francium-223 is a fifth product of the uranium-235 decay series as a daughter isotope of actinium-227; thorium-227 is the more common daughter. [23]
As of 7 Jan 2023, the "Main isotopes of <element>" tabular list will be read directly from the Isobox: "Infobox <element> isotopes". For example, {{ Infobox uranium }} will read the table live from {{ Infobox uranium isotopes }} .
This infobox contains the table of § Main isotopes, and the § Standard atomic weight. For example, {{Infobox uranium isotopes}}, as used on page Isotopes of uranium. The main isotopes table is reused in the regular Infobox: {{Infobox uranium}}.
Radioactive isotope table "lists ALL radioactive nuclei with a half-life greater than 1000 years", incorporated in the list above. The NUBASE2020 evaluation of nuclear physics properties F.G. Kondev et al. 2021 Chinese Phys. C 45 030001. The PDF of this article lists the half-lives of all known radioactives nuclides.
A table or chart of nuclides is a two-dimensional graph of isotopes of the elements, in which one axis represents the number of neutrons (symbol N) and the other represents the number of protons (atomic number, symbol Z) in the atomic nucleus. Each point plotted on the graph thus represents a nuclide of a known or hypothetical chemical element.
The darker more stable isotope region departs from the line of protons (Z) = neutrons (N), as the element number Z becomes larger. This is a list of chemical elements by the stability of their isotopes. Of the first 82 elements in the periodic table, 80 have isotopes considered to be stable. [1] Overall, there are 251 known stable isotopes in ...
