Klaproth named Uranium in tribute to the newly discovered planet "Uranus". Klaproth was experimenting with pitchblende ore, and extracted from it uranium dioxide, which he thought was pure uranium. It was later discovered that pure uranium had to be broken down more.]]> 2017-10-29 22:01:58 UTC https://padlet.com/parker_nagle/k7fvx1fhlytn/wish/201543277 parker_nagle https://padlet.com/parker_nagle/k7fvx1fhlytn/wish/201546449 Uranium's symbol is U. It has an atomic number (protons) of 92 and an atomic mass of 238.02891, which means about 146 neutrons. In the United States, Uranium reserves can be found in Arizona, Colorado, Texas, and Utah. Although other mines are also in Wyoming and new Mexico. It is often found in the form of pitchblende.]]> 2017-10-29 22:32:54 UTC https://padlet.com/parker_nagle/k7fvx1fhlytn/wish/201546449 parker_nagle https://padlet.com/parker_nagle/k7fvx1fhlytn/wish/201771749 uranium is an actinide metal. Its melting point is 1,135 degrees celsius. Boiling point is 4,131 degrees celsius. Its Density is 18.95 grams. It makes up about .00018% of earth's crust. It is a solid at room temperature]]> 2017-10-30 15:24:58 UTC https://padlet.com/parker_nagle/k7fvx1fhlytn/wish/201771749 parker_nagle https://padlet.com/parker_nagle/k7fvx1fhlytn/wish/201775929 Pure uranium is found with three isotopes; Uranium-234, Uranium-235, and Uranium 238. Uranium is toxic and radioactive, therefore it is used for nuclear weapons, nuclear fuel, nuclear submarines, and uranium glass, which glows bright green under ultraviolet (black) lights. ]]> 2017-10-30 15:31:52 UTC https://padlet.com/parker_nagle/k7fvx1fhlytn/wish/201775929 parker_nagle https://padlet.com/parker_nagle/k7fvx1fhlytn/wish/201780134

In WWII the U.S. mined on their land for the Uranium to make bombs, once the war was over they exploited and abandoned them. The environmental effects are are still controversial today.
