Plutonium (Pu)
Plutonium is the 94th element in the periodic table and has a symbol of Pu and atomic number of 94. It has an atomic weight of (244) and a mass number of 221. Plutonium has ninety-four protons and one hundred twenty-seven neutrons in its nucleus, and ninety-four electrons in seven shells. It is located in group Actinides, period seven and block f of the periodic table. Dense silvery radioactive metallic transuranic element, belongs to the actinoids. Pu-244 is the most stable isotope with a half-life of 7.6*10^7 years. Thirteen isotopes are known. Pu-239 is the most important, it undergoes nuclear fission with slow neutrons and is hence important to nuclear weapons and reactors. Plutonium production is monitored down to the gram to prevent military misuse. First produced by Gleen T. Seaborg, Edwin M. McMillan, J.W. Kennedy and A.C. Wahl in 1940.

History
Plutonium was first produced in 1940 by Glenn T. Seaborg, Edwin M. McMillan, Joseph W. Kennedy and Arthur Wahl. Plutonium-238 was produced by deuteron bombardment of uranium-238 in the 60-inch cyclotron at the University of California, Berkeley. The Berkeley team made neptunium-238 which decayed to plutonium-238. Named after the planet Pluto

| Pronunciation | ploo-TOE-ni-em (English) |
Plutonium is harmful due to its radioactivity
The atomic bomb dropped on Nagasaki, Japan in 1945 had a plutonium core
Uses
The isotope plutonium-239 is a key fissile component in nuclear weapons, due to its ease of fission and availability. Plutonium-238 has also been used successfully to power artificial heart pacemakers, to reduce the risk of repeated surgery. Plutonium-238 mixed with beryllium is used to generate neutrons for research purposes. Used in bombs and reactors. Small quantities are used in thermo-electric generators.
Sources
Found rarely in some uranium ores. Made by bombarding uranium with neutrons.
