How atomic bomb works!

An atom bomb works by initiating a nuclear chain reaction, which releases a huge amount of energy relative to conventional explosives. Per unit volume, an atom bomb may be millions or billions of times more powerful than TNT. Nuclear reactions occur when neutrons are fired at closely packed atoms with heavy nuclei (uranium or plutonium isotopes). These heavy nuclei break apart into lighter nuclei when hit by a neutron, in turn generating more neutrons which bombard other nuclei, creating a chain reaction.
