  Are you sure it’s not “mol-LIB-deh-num”?

  It all depends on how long a half-life you need to consider an isotope "stable". E.g. Xenon-124 has a half-life of 1.8x10²² years and Bismuth-209 2x10^19 years, would you consider them stable?

  Elements that have isotopes that never decay are considered stable. It’s not subjective at all; if an isotope decays radioactively, it’s unstable.

  @@TheChemNerd44 No such thing as "never"!! You didn't read or understand my comment. Bismuth-209 was considered to be stable but it is radioactive with a half life of twenty trillion years. Is that long enough for you to say "never"?

  @@TheChemNerd44 A British trillion was 10^18 but a US trillion is 10^12, so to be more definite Bismuth-209 has a half-life of 20 million million million years (= 2x10^19y). Would you consider that stable?

  @@karhukivi If it decays, then it’s unstable. It’s not a matter of “if I consider it”. It decays, so it’s unstable.

  @@TheChemNerd44 It is quite likely that all elements and all their isotopes are unstable, just a question of how long the half-life is. I'm wondering if you understand that a very long half life implies a very slow decay rate? For example the term "observationally stable" is applied to Au-197 because a decay hasn't been observed (yet) and that can be due to a very long half-life.

  Interesting! I assumed there was SOME hanging around in nature, just in insignificant quantities so it was really hard to find… Also, Molybdenum as a 5 syllable word? 😅

  Does the half life differ for each isotope and what are they?

• 
  @TheChemNerd4410 күн бұрын

  The half-life does differ for each isotope. If you're interested on the specific half-lives, the information is on ptable.com

  I thought this was a fake element at first and thought I missed out on the latest science update. It has always been there and interestingly on my paper chart it has no mass listed like the other elements, likely because no stability. I was flabbergasted
