H-bomb (hydrogen bomb)

An H-bomb, or hydrogen bomb, is a powerful nuclear weapon that releases energy through nuclear fusion, where isotopes of hydrogen (like deuterium and tritium) combine to form helium. This process releases an enormous amount of energy, much more than atomic (fission) bombs, which split heavy atoms like uranium. The hydrogen bomb uses an initial fission explosion to generate the extreme heat and pressure needed to trigger fusion. The result is a devastating explosion with significantly greater destructive power, making it one of the most powerful weapons developed.
