nuclear chemistry summary

Summary - Radioactivity Spontaneous emission of active rays by certain unstable elements. Three types of radiations are: (i) Alpha particles He 2 + ion (Helium nuclei). (ii) Beta - rays - consist of electrons. (iii) Gamma - rays - High energy electromagnetic rays. Emission of alpha partic..

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 energy produced due to the 'fission of nuclei' of certain heavier elements (such uranium), or by the 'fusion of nuclei' of lighter elements (such as hydrogen), is called nuclear energy . Nuclear reactions generate very large and powerful amounts of energy. They can be used ..

An equipment in which the nuclear chain reaction is carried out in a controlled manner is called a nuclear reactor. The energy liberated in a controlled manner is used to produce steam, which can run turbines and produce electricity. In nuclear reactors, the ..

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 fusion is a process in which lighter nuclei fuse t..

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 purposes. When a nucleus is bombarded with some sub-atomic particles suc..
