atomic bombs, and those that depend on fusion, like hydrogen bombs.
The former get their explodrogen bombs. The former get their explosive
energy from the splittings of atoms in materials like uranium of
plutonium, which takes place automatically. On the other hand,
hydrogen bombs, which are also known as thermonuclear bombs,
depend upon the fusing together of atom, as in taking place inour sun, to
