Conditions supporting nuclear fission includes the critical mass of the substance and neutrons. On Earth, the most likely fusion reaction is Deuterium–Tritium reaction. Both involve the combination and disintegration of the elemental nucleus. Distinguish between fission and fusion. A process in which two or more lighter atoms combine to create a heavy nucleus is called nuclear fusion. Fission Reaction of U 235 92 U 235 + 0 n 1 → 92 U 236 → 56 Ba 141 + 36 Kr 92 + 3 0 n 1 + Q Some other 92 U 235 fission reactions are: 92 U 235 + 0 n 1 → 54 Xe 140 + 38 Sr 94 + 2 0 n 1. Nuclear fission can be controlled through various scientific processes. In the nuclear fission reaction, the amount of energy required is less than the energy needed in a fusion reaction. As the nuclei of two light atoms are brought closer to each other, they become increasingly destabilized, due to the electric repulsion of their positive charges. The energy released in fusion is related to E = mc 2 (Einstein’s famous energy-mass equation). Nuclear fission and fusion involve the disintegration and combination of the elemental nucleus. Nuclear Fusion. <>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/Annots[ 24 0 R] /MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> One of the biggest problems is controlling the reaction when the two meet. The main difference between these two processes is that fission is the splitting of an atom into two or more smaller ones while fusion is the fusing of two or more smaller atoms into a larger one. On the other hand in nuclear fission, a nucleus like Uranium-235 and Plutonium-239 splits into lighter nuclei. Fission and fusion release huge amounts of energy. The main difference between nuclear fission and nuclear fusion is that a nuclear reaction in which a heavy nucleus is broken into smaller nuclei, by releasing neutrons and energy, is called nuclear fission. A nuclear weapon (also called an atom bomb, nuke, atomic bomb, nuclear warhead, A-bomb, or nuclear bomb) is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or from a combination of fission and fusion reactions (thermonuclear bomb).Both bomb types release large quantities of energy from relatively small amounts of matter. 16) Name the countries that have fusion technology.
