s, with the most common (~ 95.7%) nuclide (¹¹⁵In) being measurably though weakly radioactive. Its spin-forbidden decay has a half-life of 4.41×10¹⁴ years, much longer than the currently accepted age of the Universe. The stable isotope ¹¹³In is only 4.3% of naturally occurring indium. Among elements with a known stable isotope, only
