'''Fission''' is the splitting of an [[atom]]ic [[nucleus]] splits into several smaller fragments of roughly half the original [[mass]].  The process emits two or three [[neutrons]].

The sum of the fragments is slightly less than than the original mass, and the "missing" mass constitutes about 0.1 percent of the original mass.  This "missing" mass is converted into [[energy]].
