ATOMIC ENERGY IS most important source of energy now a days as it is pollution free.There are strong forces in the nuclei of atoms which keep the particles together.In two ways to release the energy hidden in the nuclei of an atom -one is by fusion and other is by splitting them.In fusion ,they are fuse with one another ,. This also occur in core of stars.Big stars produce energy by fusion of atoms.It is also done in Hydrogen bomb.Other method is splitting atoms to release energy.This is done in Nuclear power plants.for this purpose a chain reaction is required in a reactor.In this process atoms can be split by bombarding them with neutrons for example the nucleus of a uranium atom,can be split by bombarding with neutrons .A lot of energy is released in this process. along with heat.Now a days atomic energy i
