What is nuclear fusion?
Answers
In physics, 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 (neutrons or protons).
The difference in mass between the reactants and products is manifested as either the release or absorption of energy.
This difference in mass arises due to the difference in atomic binding energy between the atomic nuclei before and after the reaction.
A mechanism in which two lighter nuclei combine or merge to create a stable heavier nucleus with an immense amount of energy being emitted at the same time is called nuclear fusion.
The energy created in a fusion reaction is much greater than the energy produced in a nuclear fission reaction. Nuclear fusion happens just around 4-15 million degrees at very high temperatures. Therefore nuclear fusion is also known as thermonuclear reaction. Hydrogen bomb is based on the atomic fusion theory.
