Nuclear weapons, fissile

Nuclear weapons, fissilehttp://www.francetnp2010.fr/IMG/jpg/024-3.jpg
Fission nuclear weapons is a types of nuclear weapons strength lies in the process of nuclear fission for a heavy element such as uranium with an atomic mass number 235 (uranium-235) and plutonium with an atomic mass number 239 (plutonium -239), where these elements stimulate Altqilh shed by the fission package of neutrons to the nucleus, which lead to break apart into several parts and every component part after the fusion the initial possessed of neutrons own Matkva to stimulate fission another and continue this series of Alonctarat that are to take place normally in nuclear reactors and all the process of fission leads to the creation of large amounts of kinetic energy.
Due the beginning of this idea to the world physicist Albert Einstein, where he in 1905 published the idea of ​​special theory of relativity, according to this theory, the energy is equal to the mass of multiplied by the square of the speed of light E = mc2, according to the famous equation, the small amount of mass be equal to the enormous amount of energy, for example, can convert kg and one of the complete article to a power equal to the energy resulting from the 22 bombing of megatons of TNT and to clarify more, this equation means that any object has a mass have power even if the body in the case of stability, this equation was the main factor that revolved around the idea of ​​nuclear Aaloslhh Fbkies blocks nuclei of atoms of different elements can be estimated energy in them once hit her in the speed of light, which is a fixed number (1,079,252,848.8 km per hour or approximately 300.000 kilometers per second) .
In 1938 enables the world from Germany named Otto Hahn of the uranium atoms split into two parts by shining a package of neutrons it and after this experience has become the idea of ​​nuclear weapons in hand. The bombs and grenades materials fertilized the critical mass most important types of nuclear weapons fissile
