Pu
[pʊˈtoʊn.i.əm ]
Definition
element symbol
Pu is the chemical symbol for the element plutonium, which is a radioactive actinide metal. It is used primarily as a fuel in nuclear reactors and in the production of nuclear weapons. Plutonium has several isotopes, with plutonium-239 being the most significant for its fissionable properties. Discovered in 1940, it is named after the dwarf planet Pluto and is known for its silvery appearance and high density.

Origin of 'Pu'
Main points about word origin
- The symbol 'Pu' stands for plutonium, which was named after the dwarf planet Pluto.
- The name 'plutonium' is derived from the Latin word for Pluto, reflecting its discovery around the same time as the planet was being explored astronomically.
The term 'plutonium' derives from the name of the dwarf planet Pluto, following the naming conventions established for elements discovered in the 20th century. The name reflects the element's position in the periodic table, as it is found after uranium. Plutonium was first synthesized in 1940 by a team of scientists, including Glenn T. Seaborg, Joseph W. Kennedy, and Edwin M. McMillan, at the University of California, Berkeley. This discovery marked a significant milestone in chemistry and physics, as it opened up new possibilities for nuclear energy and weaponry. Plutonium-239, in particular, became a crucial material for atomic bombs during World War II, leading to its historical significance in the development of nuclear weapons technology. Its properties, including its ability to sustain a rapid chain reaction, have made it a subject of extensive research in both energy production and military applications.
