Nuclear Fission is the mother of Nuclear Bomb. what and How?

Nuclear fission is the process in which a large nucleus splits into two smaller nuclei with the release of energy. In the process of this division, some mass loss happens and that gets converted into energy as per the famous Mass-Energy equivalence equation given by Albert Einstein, written as,

E= m.c²

E-Energy released during process

m-loss of mass

c- speed of light (3 lakh km/second)

NUCLEAR BOMB

Image below shows the mushroom clouds generated due to nuclear bomb blast over Japan by the U.S. during 2^nd World War.

Nuclear Bomb & Nuclear Fission: It is this energy that is released during a nuclear bomb blast. During a nuclear bomb blast, Uranium gets divided into Barium & Krypton due to bombardment of a neutron, releasing enormous amount of energy.

This also released two free neutrons. These free neutrons further blast another Uranium atoms and releasing more energy. And hence, the chain continues releasing huge amount of energy.
