nuclear reactions

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

Artificial Nuclear Reactions - Radioactivity is broadly classified into two categories: a) Natural radioactivity and b) Artificial or Induced radioactivity. If a substance emits radiations by itself, it is said to possess natural radioactivity. If a substance does not possess ra..

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 nuclei and..

Nuclear fusion is a reaction in which two or more light nuclei combine to form a heavier nucleus releasing an enormous amount of energy: Nuclear fusion takes place at a very high temperature of the order of 10 7 Kelvin Hence nuclear fusion reactio..

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 fissio..

This is another important source of energy that is obtained from the energy that is stored in the nucleus of an atom. This stored energy can be obtained by carrying out two types of nuclear reactions called nuclear fission reaction and nuclear fusi..

Two consequences of nuclear reactions are the phenomena of nuclear fission and nuclear fusion. Both are important sources of nuclear energy, which may be used for peaceful or destructive purpose..

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 in its core, ..
