The Hydrogen Bomb

The Hydrogen Bomb was formed by a process called fusion. This occurs when lightweight nuclei are forced to fuse at high temperatures to form other, heavier nuclei. The temperatures need to be at millions of degrees Celsius, so the fusion occurs naturally on the sun, and other stars like it. An atomic fission bomb is used as a trigger for this reaction. Fusion can release about 4 times more energy per unit mass than fission, and because fusion is only limited by the amount of material available, it is possible for a fusion bomb to release thousands times more power than an ordinary atom bomb. This means that the bomb that destroyed Hiroshima and Nagasaki in 1945 is not nearly the most powerful nuclear weapon made. In some cases pure uranium is placed around the bomb, which then undergoes fission and creates a big radioactive explosion. In the H-bomb, deuterium and tritium, hydrogen's two heaviest isotopes, are fused to make a nuclei of helium and a neutron.

The Nuclear Equation for the Fusion:

²₁H + ³₁H à ⁴₂He + ¹₀n + energy
