Indium
Indium is a chemical element with the symbol In and atomic number 49. Indium is the softest metal that is not an alkali metal. It is a silvery-white metal that resembles tin in appearance. It is a post-transition metal that makes up 0.21 parts ...
(
49In) consists of two
primordial nuclides, with the most common (~ 95.7%) nuclide (
115In) being measurably though weakly radioactive. Its spin-forbidden decay has a half life of 4.41×10
14 years.
The stable isotope
113In is only 4.3% of naturally occurring indium. Among elements with a known stable isotope, only
tellurium
Tellurium is a chemical element with the symbol Te and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur, all three of which are chalcogens. It is occasionall ...

rhenium
Rhenium is a chemical element with the symbol Re and atomic number 75. It is a silvery-gray, heavy, third-row transition metal in group 7 of the periodic table. With an estimated average concentration of 1 part per billion (ppb), rhenium is one ...
similarly occur with a stable isotope in lower abundance than the long-lived radioactive isotope. Other than
115In, the longest-lived radioisotope is
111In, with a half-life of 2.8047 days. All other radioisotopes have half-lives less than a day. This element also has 47
isomers
In chemistry, isomers are molecules or polyatomic ions with identical molecular formulae – that is, same number of atoms of each element – but distinct arrangements of atoms in space. Isomerism is existence or possibility of isomers.

114m1In, with a half-life of 49.51 days. All other meta-states have half-lives less than a day, most less than an hour, and many measured in milliseconds or less.
Indium-111
Indium-111 (111In) is a radioactive isotope of indium (In). It decays by electron capture to stable cadmium-111 with a half-life of 2.8 days.
Indium-111 chloride (111InCl) solution is produced by proton irradiation of a cadmium target (112Cd(p,2n) ...
