Summary

The theoretically stable nuclides are those with the lowest energies among the isobars A = 1 ~ 142 (5 and 8 excluded), 156 ~ 159, 163 ~ 164.

In terms of atomic numbers or neutron numbers, they are nuclides with Z ≤ 59 (N ≤ 82) that have the lowest energies among their isobars, and ¹⁴²Nd, ^156,157,158Gd, ¹⁵⁹Tb, ^163,164Dy. 129.104.241.162 (talk) 19:26, 22 February 2024 (UTC) Cristiano Toàn (talk) 02:12, 5 March 2024 (UTC) Theoretically decay chains of nuclides of light Lanthanide elements Series 4n+1: ¹⁵³Eu =>¹⁴⁹Pm => ¹⁴⁹Sm => ¹⁴⁵Nd => ¹⁴¹Ce => ¹⁴¹Pr (stable nuclide with 82 neutrons) Sereis 4n+3: ¹⁵⁵Gd => ¹⁵¹Sm => ¹⁵¹Eu => ¹⁴⁷Pm => ¹⁴⁷Sm => ¹⁴³Nd => ¹³⁹Ce => ¹³⁹La (stable nuclide with 82 neutrons). The only natural decay chain contains electron capture process Series 4n: ¹⁵⁶Dy => ¹⁵²Gd => ¹⁴⁸Sm => ¹⁴⁴Nd => ¹⁴⁰Ce (stable with 82 neutron). Note ¹⁵⁶Dy might also undergo double electron capture to ¹⁵⁶Gd. ¹⁵²Gd might also undergo double electron capture to ¹⁵²Sm

Nuclear Isomers

The nuclides with the same number of protans(Z)and neutrons(N) or the same mass number (A) which differ in energy states are called NUCLEAR ISOMERS.' 117.228.219.243 (talk) 07:53, 29 February 2024 (UTC)

Binding Energy chart

The chart titled "Binding energy per nucleon of common isotopes" [Binding energy curve - common isotopes.svg] has a series of points indicated by either diamonds (most of them) or squares (about 20), and for the diamonds, some appear to be not quite vertically oriented. But there is no discussion anywhere associated with this chart to explain what the distinction is which is indicated by these two markers. Does anyone have a clue what this is about? 2001:56A:F0E9:9B00:68D7:C67D:3EFE:A8D1 (talk) 22:00, 18 March 2024 (UTC)JustSomeWikiReader

Swap title and redirect: Stable nuclide -> Stable isotope

I am proposing to make Stable isotope the primary topic and stable nuclide the redirect on Wikipedia:Requested_moves/Technical_requests. There I wrote:

• These are similar terms but "stable isotope" is hundreds of times more common than "stable nuclide", See google ngrams or compare searches in Google Scholar (3 million vs 140 thousand). I marked this uncontroverisial because the Talk page has no activity for 2 years.
