The working principle of atom bomb is nuclear fission. Here an uncontrolled fission reaction takes place. When the bomb explodes large quantity of energy in the form of heat, light and radiation is released, a temperature of millions of degrees and pressure of millions of atmosphere are produced. Human life is impossible under such explosion. These bombs were used in World War II and were exploded over Hiroshima and Nagasaki in Japan.

Principle
The splitting of atomic nuclei release enourmous energy. When a single free neutron strikes the nucleus of an atom of fissile material like U^235 and Pu^239, It usually knocks two or three more neutrons free energy is released when those neutrons split off from the nucleus,and newly released neutrons strilce other U^235(or Pu^239) Nuclei, splitting them in a same way,releasing more energy and more neutrons.This process is occur in the atomic bomb.
