Naturally occurring rhenium (75 Re) is 37.4% 185 Re, which is stable (although it is predicted to decay ), and 62.6% 187 Re, which is unstable but has a very long half-life (4.12×1010 years).[ 4] Among elements with a known stable isotope, only indium and tellurium similarly occur with a stable isotope in lower abundance than the long-lived radioactive isotope.
There are 36 other unstable isotopes recognized, the longest-lived of which are 183 Re with a half-life of 70 days, 184 Re with a half-life of 38 days, 186 Re with a half-life of 3.7186 days, 182 Re with a half-life of 64.0 hours, and 189 Re with a half-life of 24.3 hours. There are also numerous isomers , the longest-lived of which are 186m Re with a half-life of 200,000 years and 184m Re with a half-life of 177.25 days.[ 5] All others have half-lives less than a day.
