Plutonium is a radioactive element, it is used in nuclear reactors to generate nuclear power. The pure chemical compound of plutonium was discovered in 1962 AD. This is the first metallic element which was obtained in sufficient quantity from VK synthesis. Even today it is found only in the nuclear reactor. Plutonium is found in very small amounts of uranium ores, pitchblende, and Monazite. It is formed by the absorption of neutrons by neutron bombardment on uranium 234. These neutrons are emitted by the automatic fission of uranium. Let's know much more about the Plutonium a member Of the actinide group.
