Transcript of Pu Plutonium

Pu - Plutonium
On the Periodic Table
Plutonium is an Actinide
Heavy Metal
With a density of 19.84 g/mL, Pu has one of the greatest densities of all the elements.
MVF
MosT Valuable Fuel
Plutonium is extremely valuable as a fuel source for nuclear reactors
Because the nucleus of Plutonium is unstable, neutrons break away from it, releasing a large amount of energy
The neutrons collide with nearby Plutonium nuclei, causing them to split and in turn release more energy
Health Hazard
The radiation emitted from nuclear fisson may be powerful, but it is also harmful to life.
Plutonium does not mix well with living things
Bomb's Away
Plutonium was the fuel used for the atomic bomb dropped on Nagasaki, Japan, which ended WWII.
Winning the War?
Plutonium may have helped end WWII, but so many years later their use is now viewed by many as controversial.
Melting Point 640 C
Boiling Point
3228 C
Plutonium has 7 electron shells, making it a very large atom
The continuous generation of heat from a controlled nuclear reaction is the basis for nuclear-powered electical production.
Pu exists in very small amounts in nature, but it is mostly synthesized by bombarding Uranium atoms with hydrogen nuclei.
Pu wa chemically identified in early 1941 by Glenn Seaborg and his research team out of the University of California, Berkeley.
Plutonium cannot be mined from the ground, but Uranium can
After Uranium is extracted from its ore, the pure element can then be converted into Plutonium when Hydrogen-2 atoms bombard Uranium nuclei
Discovery and Production
Plutonium production has created a highly toxic environment in and around production facilities and has proven to be a challenge to clean up.
Reactivity
Plutonium is highly reactive and will form a number of compunds with Group 16 & 17 elements, such as Plutonium Tetrafluoride and Plutonium Oxide
References
Unlike nuclear fission in a reactor, the fission in a bomb occurs all at once.
The instantaneous release of energy creates so much heat that it vaporizes matter close enough to the explosion.
