Element 160-166

edit

Hi, there have been ongoing discussions about new elements being found in a distant asteroid. If these turn out to be stable but rare on Earth, should they be classed as natural isotopes? Its possible that 232Th might be one of the decay products and this might explain the relative abundances of some isotopes. 88.81.140.241 (talk) 05:55, 12 August 2024 (UTC)Reply

I am extremely skeptical that an element with such a high atomic number could be stable, but there has been some speculation about a second island of stability around element 164. If such elements can somehow be produced by astrophysical processes but they do not occur on Earth, the appropriate classification would be cosmogenic.
