Plutonium

Plutonium (Pu) is a silvery colored radioactive metal that has the atomic number 94 in the periodic table. It is an Actinoid Metal with the symbol Pu.

Plutonium as a. major focus of the Manhattan project in World War 2 due to its use in atomic bombs. It was discovered by Glenn Seaborg, Edwin McMillan, Joseph Kennedy, and Arthur Wahl in 1941 when they bombarded uranium with deuteron at the University of California Berkeley. Plutonium is one of the first synthetic elements made in the lab that was produced in large quantities. It is named after the planet pluto. Plutonium is used in nuclear reactors and nuclear bombs as it. undergoes chain reactions during its nuclear decay. It is widely used in space exploration as well on rovers and satellites. it is not found elementally in the earth’s crust but found in minerals containing uranium. It is a solid metal at room temperature and it has a melting point of 639°c and a boiling point of 5842°c. Plutonium is often transported by sea but has also been known to be flown on commercial planes. In 2012 media coverage uncovered the transport of plutonium on passenger planes in Norway.
