Two to three neutrons are also emitted in the process. About 0.1 percent of the original mass is converted into energy. Fission can happen spontaneously or by bombarding a nucleus with neutrons. Atomic weapons are created by harnessing the sudden release of energy produced by splitting the nuclei of an atom, usually either uranium-235 or plutonium-239.</ins></div></td></tr>
