'''Nuclear transmutation''' is the conversion of one [[element]] into a different element. Nuclear transmutation is observed to happen either [[nuclear reaction]]s with other particles or through [[radioactive decay]]. Transmutations can occur either naturally or through artificial means.
Artificial nuclear transmutation was first demonstrated by the [[Cockcroft and Walton Experiment|Cockcroft-Walton experiment]] conducted in 1932. In which atoms of lithium-7 were split into [[alpha particles]] accompanied by a release of energy.
