Fission is a process in which a heavy nucleus of an element splits into two or more stable elements. This fission reaction is associated with the release of energy. For example, the process of U235 fission is triggered by hitting U235 by a slow-moving neutron. It gives Barium( 144), Krypton (89) and three neutrons along with 210Mev of energy.

Fusion: Two light elements such as Hydrogen nucleus fu... more

Fission is when an unstable nucleus spontaneously decomposes into two or more smaller, more stable nuclei. Eg: Uranium-235 undergoes nuclear fission to become Barium-139 and Krypton-94 plus 3 neutrons. In summary a big unstable nucleus falls apart (decays) and becomes two or more smaller nuclei.

Fusion is when two or more small nuclei fuse together to form a bigger nucleus. E.g. Hydrogen nuclei... more
