Atomic Bomb. Nuclear fission produces theatomic bomb, a weapon of mass destruction that uses power released by the splitting ofatomic nuclei. When a single free neutron strikes the nucleus of an atom of radioactive material like uranium or plutonium, it knocks two or three more neutrons free.

Definition: Fission 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.
Natural occurrence of the process: Fission reaction does not normally occur in nature. Fusion occurs in stars, such as the sun.
Byproducts of the reaction: 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.
Conditions: Critical mass of the substance and high-speed neutrons are required. High density, high temperature environment is required.
Energy Requirement: Takes little energy to split twoatoms in a fission reaction. Extremely high energy is required to bring two or more protons close enough that nuclear forces overcome their electrostatic repulsion.
Energy Released: The energy released by fission is a million times greater than that released in chemical reactions; but lower than the energy released bynuclear fusion. The energy released by fusion is three to four times greater than the energy released by fission.
Nuclearweapon: One class of nuclear weapon is a fission bomb, also known as anatomic bomb or atom bomb. One class of nuclear weapon is thehydrogen bomb, which uses a fission reaction to "trigger" a fusion reaction.
This is known as a chain reaction and is what causes an atomic explosion. When a uranium-235 atom absorbs a neutron and fissions into two new atoms, it releases three new neutrons and some binding energy. Two neutrons do not continue the reaction because they are lost or absorbed by a uranium-238 atom.
