The Full Story
Plutonium is an actinide with atomic number 94, usually shown in the separate bottom row of the periodic table. It is primarily synthetic, though trace amounts occur naturally in uranium ores through rare nuclear processes. Plutonium was first produced in 1940 and became historically important during the development of nuclear weapons and reactor fuel cycles. Several isotopes of plutonium are highly radioactive, especially plutonium-239.
