The process of nuclear fission can be understood on the basis of liquid drop model proposed by Yakov Frenkel, Neils Bohr and John Wheeler. In this model, nucleus of U-235 is treated as a positively charged, non-compressible drop of a liquid which is enclosed by a thin...

If the nuclear reaction is made to take place in a controlled manner, then the energy released during this reaction can be used for peaceful purposes. A nuclear reaction can be controlled by using rods of cadmium and boron. We know that when a slow moving neutron...

We have already discussed that when a slow moving neutron hits a nucleus of U-235, three neutrons are produced. These three neutrons can strike with three more nuclei of U-235 to produce 9 neutrons, which in turn can bring about fission of nine nuclei of U-235 to...

Nuclear fission is the process of splitting of a heavy nucleus into a number of lighter nuclei with the liberation of a large amount of energy. For example, when uranium 235 is bombarded with slow moving neutrons, it breaks up into two light-weight atoms barium 141...

At present we are aware about 118 elements. Out of these 118 elements, first 92 elements i.e. the elements up to uranium are found in nature. This means that elements from Hydrogen (having atomic number 1) to Uranium (having atomic number 92) are naturally occurring...
