Describe the working of a hydrogen bomb.

The hydrogen bomb consists of heavy isotopes of hydrogen called deuterium and tritium along with lithium-6. Atom bomb is used for the explosion of hydrogen bomb. While the atom bomb is exploded, since its fission reaction a lot of heat is produced which raises the temperature of deuterium and tritium to 107°C in a few microseconds. Then fusion reactions of deuterium and tritium take place which produces a tremendous amount of energy. This explodes the hydrogen bomb. Lithium-6 is used to produce more tritium needed for fusion.
