Interested in self-hosting, decentralization, and learning more about the fediverse.

I also do photography, but with digital cameras from the 90’s.

  • The “island of stability” actually encompasses many of the superheavy elements that we have already produced. The “stability” part comes from “magic numbers” of neutrons in the isotopes that are theorized to have some kind of stabilizing effect on the nuclear shells.

    The difficulty is that we can theorize the number of neutrons we need to stabilize a certain number of protons, but finding atoms with the right number of protons and neutrons to smash together to hopefully create that total number is… difficult. Sometimes those particular isotopes with the proton/neutron quantities required either just plain don’t exist, or are themselves a wholly synthetic isotope with its own set of problems like being insanely slow or difficult to produce, having a crazy short half-life, incompatibility with various acceleration methods, etc.


  • The elements at the very end of the periodic table are somewhat tenuous as we know “elements” to be, as there has only ever been very VERY small amounts of this material produced, and the isotopes of those materials that ARE produced split apart almost immediately with insanely small half-lives, so it’s not like there’s any amount of it just kicking around in a jar somewhere in some lab.

    There’s a ton of interesting reading on the theoretical island of stability in superheavy elements, where a special number of neutrons added to the isotope can possibly make these superheavy elements stable for a macroscopic amount of time so they could actually be studied and handled instead of instantly exploding apart and only being detected through their decay products.

    I think there are elements with experiments designed to produce them up to around atomic number 125 or 127. Currently the highest confirmed, named, and somewhat categorized is 118. There’s info out there about the theoretical elements. Here’s the page for element 119. https://en.wikipedia.org/wiki/Ununennium. Purely theoretically, you could just keep adding rows to the periodic table, and it will keep going, but most of those materials will never actually exist or never could exist. It’s kind of like theoretical vs applied math.
