NUCLEAR FISSION MEANING HOW TO

In cases where the interacting nuclei belong to elements with low atomic numbers (e.g., hydrogen or its isotopes deuterium and tritium), substantial amounts of energy are released. Nuclear fusion is the process by which nuclear reactions between light elements form heavier elements. Scientists believe fossilized skulls of elephant relatives found by ancient Greeks were the basis for the mythological Cyclops. If uncontrolled, as in the case of the so-called atomic bomb, it can lead to an explosion of awesome destructive force.

If controlled in a nuclear reactor, such a chain reaction can provide power for society’s benefit.

These neutrons can induce fission in a nearby nucleus of fissionable material and release more neutrons that can repeat the sequence, causing a chain reaction in which a large number of nuclei undergo fission and an enormous amount of energy is released. In the fission process a large quantity of energy is released, radioactive products are formed, and several neutrons are emitted. The process may take place spontaneously in some cases or may be induced by the excitation of the nucleus with a variety of particles (e.g., neutrons, protons, deuterons, or alpha particles) or with electromagnetic radiation in the form of gamma rays. breaks up into two lighter nuclei of roughly equal mass. In nuclear fission the nucleus of an atom, such as that of uranium or plutonium. Nuclear energy has been released explosively by both nuclear fusion and nuclear fission. Another method for obtaining nuclear energy, controlled nuclear fusion, holds promise but has not been perfected by 2020. One method of releasing nuclear energy is by controlled nuclear fission in devices called reactors, which now operate in many parts of the world for the production of electricity. It is distinct from the energy of other atomic phenomena such as ordinary chemical reactions, which involve only the orbital electrons of atoms. Nuclear energy, also called atomic energy, energy that is released in significant amounts in processes that affect atomic nuclei, the dense cores of atoms.
