#but maybe the ones where the most stable isotopes have half-lives measured in microseconds need like idk an asterisk next to them

the elements at the end of the periodic table barely feel like real elements to me. idk, if you can't hold a lump of it in your hand without it exploding due to radioactivity--man, radioactivity is barely the right word, it's a loose mass of neutrons and protons that only just holds together for a few microseconds--you can't do chemistry with it. it's not a chemical element, in the sense it is not found as part of any compounds on Earth or in space, because it does not exist long enough to form chemical bonds. i get that you wanna finish out the last period, make the bottom right corner nice and square. but you're not doing chemistry. you're doing Stupid Particle Accelerator Tricks.
