![]() The release of energy in the case of lighter nuclei is due to the interplay of two opposite forces nuclear force between the protons and the neutrons and the Coulomb force between protons.There is a difference in the combined mass of the lighter nuclei and the produced heavier nuclei as some mass is released in the form of energy.Thus, the nuclear fusion of lighter nuclei is an exothermic reaction, whereas that of heavier nuclei results in an endothermic reaction.Usually, if a fusion process produces nuclei lighter than iron or nickel, energy is released. Nuclear fusion can either release large amounts of energy to absorb energy depending on the resulting nuclei.Nuclear fusion is a type of nuclear reaction where two or more light atomic nuclei combine to form heavier nuclei and subatomic particles. Nuclear Fission vs Nuclear Fusion Nuclear Fusion Definition Common heavy elements that undergo both spontaneous fission and induced fission include Uranium, thorium, and plutonium.Nuclear fission can occur spontaneously in the form of radioactive decay or as nuclear reaction as a bombardment process.The products of nuclear fission are primarily unpredictable, which distinguishes the process from other similar reactions like alpha decay and cluster decay, where the same products are produced each time.The nuclear chain reactions produce an enormous amount of energy which can be used to power communities when controlled but can also result in an explosion if left uncontrolled.Such fission reactions can result in a chain reaction where a large number of nuclei undergo fission in a sequence as a result of the emitted neutrons from the previous fission.Most nuclear fissions are binary fissions producing two equal halves however, some fissions result in three or more fragments. ![]()
