Nuclides with atomic number of 75 but with different mass numbers
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
(4.12×10
10
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.
