Which term is used to describe a weapon that releases energy from splitting atoms?

• A. Appeasement
• B. Atomic Bomb/Nuclear Bomb
• C. Axis Powers
• D. Battle of Midway

Answer: (B)

This tests understanding of how energy is released in a weapon. A device that releases energy by splitting atoms relies on nuclear fission, so the term that fits is an atomic bomb (also called a nuclear bomb). When heavy nuclei like uranium-235 or plutonium-239 are forced to split, they trigger a rapid chain reaction that releases an enormous amount of energy in a very short time. This is fundamentally different from chemical explosives, which derive energy from rearranging electrons in chemical bonds and are far less powerful. The other options refer to diplomacy or historical events, not a weapon or its mechanism. So the correct term is atomic bomb (nuclear bomb).
