# Have we found stable, super-heavy elements?

Have we found a stable super heavy element or created one in a lab, or are they still hypothetical?

• More sci-fi then hypothetical. There's no reason to think any superheavy nuclide wouldn't be highly radioactive (half-life measured in minutes, at most). – Mithoron Oct 14 '17 at 0:21
• It depends on how you define "stable." The notion is that there is a region of super heavy isotopes that would have a longer half-life than isotopes which are lighter or heavier. But the "stable superheavies" won't be as stable as say helium-4. – MaxW Oct 14 '17 at 0:29

• I thought superheavies have $Z \geqslant 104$, so actinides are supposed to be out of scope. – andselisk Oct 14 '17 at 6:19
