Nuclear reactions, also known as nuclear processes, are those processes in which the nuclei of atoms and sub-atoms combine and transform. The nucleus can also fragment, which can determine the type of reaction that is being studied. These can be both exothermic, that is, during the abrupt changes it goes through, it releases large amounts of energy, and endothermic, where the energy is, on the contrary, absorbed; this depends on whether they need energy to be produced or whether, well, they are only created to give off energy. We can also speak of a nuclear chain reaction, one that is caused by fission (nuclear reaction), which a neutron causes a fissile atom.
Among the forces that intervene during the nuclear reaction process, there are: strong nuclear: it is the force that maintains the nuclear bonds; as discovered by some scientists, it is the best known variant of this magnitude in nature. The weak nuclear, for its part, has a similar function to that already mentioned; Usually this has a very short range and is 1013 times less strong than the nuclear strong. Electromagnetic is only 100 times less strong than strong nuclear; it has an infinite scope. The gravitational force, for its part, is a weak and very short-range force, however, it is always attractive; It does not have much influence on the reactions because it is 1038 times weaker than the strong nuclear one.
In nuclear reactions, certain types of protons are involved, such as: bosons, fermions, hadrons (which are subdivided into mesons and baryons), leptons, quarks and antiparticles.
