Hydrogen Bomb vs. Atomic Bomb — What's the Difference?
By Tayyaba Rehman — Published on November 3, 2023
The hydrogen bomb (H-bomb) uses fusion of hydrogen isotopes, producing a much larger explosion, while the atomic bomb (A-bomb) relies on fission of atomic nuclei like uranium or plutonium.

Key Differences
Both the hydrogen bomb and atomic bomb are nuclear weapons, but their operational mechanisms differ significantly. The hydrogen bomb utilizes fusion, where lightweight nuclei, typically isotopes of hydrogen, are combined under extremely high temperatures and pressures.
On the other hand, the atomic bomb exploits the process of fission, where heavier atomic nuclei like uranium or plutonium are split into smaller parts. The energy released during fusion in a hydrogen bomb is considerably higher than fission in an atomic bomb. This makes the H-bomb vastly more powerful. Despite their differences, a hydrogen bomb often uses an atomic bomb as a trigger to achieve the necessary conditions for fusion.
Both weapons are devastating, with the capability to cause unparalleled destruction, but the hydrogen bomb is often viewed as the more advanced and potent of the two.
