nuclear energy chemistry

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 ..

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..

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 par..

Nuclear Reactors - 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 ..

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..

The first ionization energies of the group 15 elements are higher than the corresponding members of the group 14 elements. Explanation: The larger ionization energy is due to greater nuclear charge, small size and stable configuration of the atoms of group 15 elements..

The Sun radiates energy in the form of heat and light. We utilize these forms of energy either directly or indirectly, after conversion into some other forms. Utilization of solar energy in various ways is as represented. Besides the primary role of the Sun's ..
