. D m the mass defect or the mass converted into energy is given by D m = 236.127 - 235.846 = 0.281 amu 1 amu = 931.48 MeV \ Energy released = 0.281 amu = 931.48 x 0.281 = 261.75 MeV The neutrons emitted from the fission of first uranium atom hit other uranium nuclei and cause their fissi..

Once the nucleus has been divided by fission, the neutrons that are emitted can strike other nuclei. This energy released is extremely large. The neutrons produced during the fission are called secondary neutrons. These neutrons may bring about the fission of three more 9 2 U 2 3 5 ..

The process of splitting of a heavy nucleus into a number of light nuclei with the liberation of tremendous amount of energy and two or three neutrons is called nuclear fission. In the fissioning of the Uranium-235 isotope, some mass of Uranium disappears (or is lost) and th..

Conclusion - Rutherford's alpha particle scattering experiment explained the structure of atom and the size of nucleus. The Bohr's model explained the hydrogen spectrum. Radioactivity occurs due to nuclei being unstable resulting in the emission of three types of radiations having differe..

Nuclear reactions are those reactions where in a nucleus when bombarded with nucleons or other sub-atomic particles; undergoes a change in its compositio..

The sun is the most enormous and direct, source of energy. Where does this enormous energy that the sun radiates come from? The source of this energy was not known to mankind until the year 1939. It was a German physicist, Hans Bethe, who proposed that the sun contains hydrogen nuclei..

. Hahn and Strassman discovered that when 9 2 U 2 3 5 is bombarded with thermal neutrons, it splits up into 5 6 Ba 1 4 1 and 3 6 Kr 9 2 with emission of three neutrons along with 200 MeV of energy per fission. This energy appears in the form of g -ray..

Nuclear Fusion - The fission of heavy nuclei is accompanied by mass losses resulting in the liberation of large amounts of energy. Similarly, the fusion of light nuclei is accompanied by mass losses and the evolution of large quantities of energy. Nuclear fus..

Nuclear Reactors - A nuclear reactor is a device for obtaining and using the energy from a controlled nuclear chain reaction. Controlled means the rate or speed of the nuclear fissions can be changed by the operator. Most reactors are constructed in..
