Also called "H-bomb" or "fusion bomb", the hydrogen bomb is the most powerful explosive invented by man. Its force can reach 50 times that of an atomic bomb like those that were dropped on Japan and the reaction is the same that occurs spontaneously inside stars like the sun.
In contrast to what happens in nuclear fission, when heavy uranium atoms "break" releasing large amounts of energy, in nuclear fusion the hydrogen atoms (deuterium and tritium) come together to release energy.
The difference is that while nuclear fission releases about 10% of the energy contained in the nucleus of atoms, fusion can release about 40% of that energy.
