H Bomb. Abbreviation for Hydrogen Bomb. The hydrogen bomb is the big brother of the first nuclear bombs, Fat Man and Little Boy, which were dropped on Nagasaki and Heroshima in 1945. The hydrogen bomb uses a hydrogen neutron, fired at high speed, into an atom of some unstable element, usually uranium.
The difference between a hydrogen bomb and a regular uranium or plutonium bomb is that a hydrogen bomb uses fusion instead of fission to generate the main explosion.n a fusion reaction, two atoms of the lightest element, hydrogen, fuse to create one atom of helium, the next-lightest element â and release much more energy.
