Curium is the chemical element with atomic number 96 and symbol . It is a actinide. It has no stable isotopes and is produced through nuclear transformations. Its common trivalent chemistry helps organize its separation from other actinides, while its radioactive decay gives it physical behavior absent from a stable chemical analogue.[ref]
