nuclear chain reactions

A nuclear chain reaction occurs when on an average more than one neutron from a nuclear fission reaction causes another fission reaction. The reaction taking place in an atom bomb is an uncontrolled chain reaction..

. 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 fission resulti..

Two organic compounds having same molecular formula differ in the nature of the carbon atom chain. This kind of isomerism is known as chain or nuclear isomerism. For e.g., n-butane and isobutane, have the same molecular formula C 4 H 1 0 . While n-butane is a straigh..

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 a similar ma..

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 reac..

Nuclear reactor is a furnace or an equipment in which the nuclear chain reaction is carried out in a controlled manner and the heat energy so liberated is converted into electricity. Boiling Water type Nuclear React..

. This difference in mass appears as energy given by [c is the velocity of light] The Uranium - 236 can fission to give isotopes of Barium-144, Krypton - 90 and two neutrons. Nuclear Fission Uranium - 236 can also divide to produce other products. Fission in uranium atoms may result in a ..

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..
