  2. Thermonuclear bomb, weapon whose explosive power results from an uncontrolled self-sustaining chain reaction in which isotopes of hydrogen combine under high temperatures to form helium in a process known as nuclear fusion.

  3. Sep 22, 2017 · A hydrogen bomb has never been used in battle by any country, but experts say it has the power to wipe out entire cities and kill significantly more people than the already powerful atomic...

  4. What is Hydrogen Bomb. The hydrogen bomb (or) h bomb is also known as the thermonuclear bomb. These bombs have greater destructive power compared to atomic bombs. These hydrogen bombs are the result of nuclear fusion reactions.

  5. Aug 17, 2023 · A hydrogen bomb , also known as a thermonuclear bomb or fusion bomb, is an explosive device that uses the energy released by the nuclear fusion of hydrogen to generate an extremely powerful explosion.

  6. hydrogen bomb, or H-bomb or thermonuclear bomb, Weapon whose enormous explosive power is generated by the nuclear fusion of hydrogen isotopes. The high temperatures required for the fusion reaction are produced by detonating an atomic bomb (which draws its energy from nuclear fission ).
