At the behest of the physical nuclear, which is that branch of the physical which is dedicated to the analysis of the reactions and characteristics corresponding to the atomic nuclei, fission names that nuclear reaction in which the nucleus of a heavy atom splits into two or more nuclei of lighter elements and presents a huge release of Energy.
It should be noted that the fission of heavy nuclei is a exothermic process, a situation that entails the release of significant amounts of energy, for example, the aforementioned process generates much more energy with respect to that released in conventional chemical reactions, while the energy is transmitted in form of gamma radiation or Kinetic energy, of those fragments of the fission that will heat the matter that is around the space where it is produced.
There are several methods by which fission can be induced, including that of the core bombardment of a fissionable atom with a particle correct energy. The other particle is generally a
neutron free, which is absorbed by the nucleus making it unstable, then, due to this instability, it will end up splitting into two or more pieces.The products that result from nuclear fission are extremely radioactiveTherefore, it is necessary to take the necessary precautions to avoid accidents or future complications.
The nuclear fission of the atoms became a reality in the year 1938 thanks to the research of scientists Lise Meitner, Friedrich Wilhelm "Fritz" Straßmann and Otto Hahn. Even, Hahn received the Nobel Prize in Chemistry for his discovery in this regard, in 1944.
A concept linked to fission is that of chain reaction, such a situation happens when a event fission begins by releasing two and three neutrons on average as by-products, while the neutrons escape in various directions at random and in that way they hit other nuclei, prompting them to undergo fission.
