\t\t\tFission is the splitting of a large atom into two or more smaller ones.Fusion is the fusing of two or more lighter atoms into a larger one.Fission reaction does not normally occur in nature.Fusion occurs in stars, such as the sun.Fission produces many highly radioactive particles.Few radioactive particles are produced by fusion reaction, but if a fission "trigger" is used, radioactive particles will result from that.Critical mass of the substance and high-speed neutrons are required.High density, high temperature environment is required.Takes little energy to split two atoms in a fission reaction.Extremely high energy is required to bring two or more protons close enough that nuclear forces overcome their electrostatic repulsion.The energy released by fission is a million times greater than that released in chemical reactions, but lower than the energy released by nuclear fusion.The\xa0energy\xa0released by fusion is three to four times greater than the energy released by fission.One class of nuclear weapon is a fission bomb, also known as an atomic bomb or atom bomb.One class of nuclear weapon is the hydrogen bomb, which uses a fission reaction to "trigger" a fusion reaction.Fission is used in nuclear power plants.Fusion is an experimental technology for producing power.Uranium is the primary fuel used in power plants.Hydrogen isotopes (Deuterium and Tritium) are the primary fuel used in experimental fusion power plants.\t
