Natural indium is a mixture of two isotopes: indium-113 (4.28 percent) and indium-115 (95.72 percent). Indium metal is unaffected by air at ordinary temperatures, but at a red heat it burns with a blue-violet flame to form the yellow oxide In2O3. This oxide is easily reduced to the...

Main article: Isotopes of indium Indium in nature consists of two primordial nuclides. One unusual property of indium (shared only with rhenium) is that although it possesses a stable isotope, its most common (abundant) isotope (95.7%) is slightly and measurably radioactive. This isotope, indium...
Seventy isotopes and isomers are now recognized (more than any other element). Natural indium contains two isotopes. One is stable. The other, 115In, comprising 95.71% of natural indium is slightly radioactive with a very long half-life. Uses In bearing alloys; as a thin film on moving ...
