Question

Write the principle behind the Hydrogen Bomb.

Answer 1

Hint: Nuclear reactions are classified into two types: Nuclear fission and Nuclear fusion. The principle behind the Hydrogen Bomb, can be determined using the concept of classification of the nuclear reactions.

Complete step-by-step answer:
The hydrogen bomb is based on the fusion reaction of hydrogen to form helium producing a large amount of energy. Hydrogen bomb consists of an arrangement for nuclear fission in the centre surrounded by a mixture of deuterium and tritium isotope. Fission reaction provides the high temperature necessary to start the fusion.

So, we can say that the principle behind the Hydrogen Bomb is nuclear fusion.

Additional Information:
Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles. The difference in mass between the reactants and products is manifested as either the release or absorption of energy.

Nuclear Fission is a process in nuclear physics in which the nucleus of an atom splits into two or more smaller nuclear fission products and usually some byproduct particles. Hence, fission is a form of elemental transmutation.

Note: It has been observed by the physicists that a fusion reaction of the nuclei takes place in stars like the sun and an enormous amount of energy is produced in the form of heat and light. The process is that if 4 hydrogen nuclei are used to make a helium nuclei an enormous amount of energy is released which is about 25 MeV of energy per fusion.
If the fusion reaction can be conducted in a controlled manner it takes the form of a devastating bomb.
