Isotopes of indium

Indium has two stable isotopes: \(^{113}\text{In}\) and \(^{115}\text{In}\). 1. **\(^{113}\text{In}\)** - This isotope has a natural abundance of about 4.3%. It is a stable isotope, meaning it does not undergo radioactive decay. 2. **\(^{115}\text{In}\)** - This isotope is the most abundant, accounting for about 95.

Indium-111 (^{111}In) is a radioactive isotope of indium. It has a half-life of about 2.8 days and decays primarily via electron capture to stable tin-111 (^{111}Sn). Indium-111 is of significant interest in the field of nuclear medicine, particularly for its applications in diagnostic imaging and targeted therapy.
