WebWJEC Nuclear decay and nuclear energy Nuclear fission is the splitting of a radioactive nucleus to release energy. High-energy collisions between light nuclei can result in fusion, which... WebFeb 13, 2024 · nuclear fission, subdivision of a heavy atomic nucleus, such as that of uranium or plutonium, into two fragments of roughly equal mass. The process is accompanied by the release of a large amount of energy. In nuclear fission the nucleus of an atom breaks up into two lighter nuclei. The process may take place spontaneously in …

Webv. The lesser amount of binding energy for lighter and heavier nuclei explains nuclear fusion and fission respectively. A large amount of energy will be liberated if lighter nuclei are fused to form heavier one (fusion) or … WebA material whose nuclei can split by nuclear fission e.g. uranium and plutonium Spontaneous fission The spontaneous splitting of a large and unstable nucleus (very rare) Uranium-235 An unstable, fissionable isotope of uranium that is used in most nuclear reactors Neutron (slow-moving)
WebApr 1, 2024 · Fusion. Fusion occurs when two atoms slam together to form a heavier atom, like when two hydrogen atoms fuse to form one helium atom. This is the same process that powers the sun and creates huge amounts of energy—several times greater than fission. It also doesn’t produce highly radioactive fission products. WebFission Reactions. In a fission reaction, energy is produced when a single large radioisotope splits into two smaller nuclei and subatomic particles, such as neutrons. Because a single reactant is present in a fission reaction, this transformation can be categorized as a decomposition reaction.Furthermore, while no radiation is generated …
