![]() Fusion of nuclei with lower mass than iron releases energy while fusion of nuclei heavier than iron generally absorbs energy. The reaction is followed either by a release or absorption of energy. In a fusion reaction, on the contrary, two light nuclei stick together to form a heavier nucleus, as shown in Fig. Nuclear fusion is the joining of two nuclei to form a heavier nuclei. Control rods - Rods made of chemical elements capable of absorbing many neutrons, that are used to control the rate of a fission chain reaction in a nuclear reactor.\( \newcommand\ J\).Fusion - A nuclear reaction in which nuclei combine to form more massive nuclei with the simultaneous release of energy. Nuclear fusion is a process where two light nuclei combine to form one heavier nucleus, releasing energy in the process.Fission - A nuclear reaction in which a heavy nucleus splits into two or more smaller fragments, releasing large amounts of energy.Critical mass - The smallest mass of a fissionable material that will sustain a nuclear chain reaction at a constant level.Chain reaction - A multi-stage nuclear reaction that sustains itself in a series of fissions, in which the release of neutrons from the splitting of one atom leads to the splitting of others. Fission: A nuclear reaction in which a heavy nucleus splits into two or more smaller fragments, releasing large amounts of energy.Fusion is the process that powers active stars, releasing large quantities of energy. Nuclear fusion is when two small, light nuclei collide and join together to make a heavier nucleus. During this process, matter is not conserved because some of the mass of the fusing nuclei is converted to energy, which is released. Nuclear radiation also has many medical uses. Nuclear fusion is the process by which two or more atomic nuclei join together, or fuse, to form a single heavier nucleus. ![]() nuclear fission because the resulting products are not radioactive. nuclear fusion because a large amount of energy is. nuclear fission because an atom is splitting into two large fragments of comparable mass. In the reaction, the matter is not conserved because some of the mass of the fusing nuclei is converted to energy. nuclear fusion because nuclei combine to form a heavy nucleus. Fission mostly occurs by the collision of a neutron with the nuclei. Nuclear fusion is when two or more atomic nuclei fuse to form a single heavier nucleus. Nuclear fusion is the process by which two light atomic nuclei combine to form one heavier atomic nucleus. The splitting of a nucleus into 2 nuclei is called nuclear fission. ![]() It is an exothermic process that leads to the release of energy. Artificial transmutation of elements can be accomplished by bombarding the nuclei of some elements with alpha or subatomic particles. Fusion is defined as the combination of 2 nuclei that fuse in order to form heavier stable nuclei. Fusion combines atomic nuclei and fission splits nuclei. Naturally radioactive elements exist in the earth and are either alpha or beta emitters. In a nuclear fusion reaction, two small, light nuclei combine to form one larger, heavier nucleus. \)-235 disintegration, the fission will be self-sustaining. ![]()
