Hydrogen-bomb
noun
1.
a bomb, more powerful than an atomic bomb, that derives its explosive energy from the thermonuclear fusion reaction of hydrogen isotopes.
noun
1.
a type of bomb in which energy is released by fusion of hydrogen nuclei to give helium nuclei. The energy required to initiate the fusion is provided by the detonation of an atomic bomb, which is surrounded by a hydrogen-containing substance such as lithium deuteride Also called H-bomb See also fusion bomb
hydrogen bomb
An extremely destructive bomb whose explosive power is derived from the energy released when hydrogen atoms are fused to form helium. This atomic fusion reaction is the same reaction that takes place in stars like the Sun, where the pressure of gravity forces hydrogen atoms to fuse; a hydrogen bomb uses the force of an atomic explosion (the fission reaction exploited in atomic bombs) to compress the hydrogen to the point where fusion takes place. Hydrogen bombs are many times more powerful than atomic bombs.
A nuclear weapon with enormous explosive power, fueled by nuclear fusion, in which atoms of hydrogen combine to form atoms of helium.
