| Nov 3 at 14:38 | comment | added | Jon Custer | A fully stripped nucleus is still an element. But the limits keep being tested, and nuclear models are complicated for high Z elements. Maybe there is an island of stability, maybe not. And very weird nuclei may fleetingly exist in supernovae. Glen Seaborg would approve of this question… | |
| Nov 2 at 1:05 | comment | added | Mithoron | @PaulKolk Well, technically bismuth also decays, but extremally slowly. No one would say it means it's not an element. If decay time is too short for nucleus to capture a single electron... that's a different matter. | |

| Nov 1 at 13:44 | comment | added | Paul Kolk | What kind of "chemical factors" ? Experimentally, bismuth, element number 83, is the last one within permissible radioactivity limit, IMO. Surprisingly, answers do not even mention this. Please make it clear how high radioactivity is permissible. | |
