What element was used as fuel for the "Fat Man" bomb?

Explanation:
The main idea is identifying which fissile material powered Fat Man. Fat Man used plutonium-239 as its fuel. The bomb was an implosion device, with a plutonium core that was symmetrically compressed by explosive lenses to reach a supercritical state and start the chain reaction. Plutonium-239 was chosen because it can be produced in reactors and formed into a compact, uniform pit ideal for this implosion design. Uranium-235, by contrast, was used in the other bomb with a different gun-type mechanism, while thorium and neptunium were not used as the primary fissile fuel for Fat Man.
