I’m not able to verify who “Reade Richard” refers to from the available information, so I can’t confidently name the isotope. The closest relevant result suggests a 2025 report about scientists recreating the universe’s first molecule, helium hydride, but that is not an isotope discovery.

What I could confirm

  • A recent science article says researchers recreated the first molecule ever to form, helium hydride.
  • I did not find a reliable match for “Reade Richard” in the available results, so the isotope part appears unclear or possibly misstated.

Best next step

  • If you can share the exact article, post, or a corrected name, I can identify the isotope precisely.
