  1. Uranium By: Josiah Kim

  2. Where is Uranium found on the Periodic Table of Elements? Right there. Element number 92.

  3. General Information • Element name: Uranium • Symbol: U • Atomic number: #92 • Atomic weight: 238.029 • Atomic Volume: 12.59cm³/mol • Density: 19.05 g/cc • Melting point: 1408°K (1135°C) • Boiling point: 4403°K (4130°C)

  4. General Information • State of Matter: Solid • Color: Silvery-white • Classification: Radioactive rare earth element (Actinide Series) • Name origin: After the planet Uranus • Where can it be found: In various places. Like pitchblende, carnotite, cleveite, autunite, uraninite, uranophane, tobernite, phosphate rock, lignite, monazite sand • Discoverer: Martin Klaproth. • Date of Discovery: 1789 in Berlin, Germany.

  5. Description of Uranium • Is dense • Is a metal • Is a solid • Is lustrous • Is malleable • Is ductile • Is radioactive • Is silvery-white • Is slightly paramagnetic • Is heavy

  6. Uses of uranium • One way uranium is used is to help harden and strengthen steel • Another way uranium is used for is in gyrocompasses, compasses that find true north • Uranium is also used as counterweights for planes’ control surface • Uranium is used for x-rays and nuclear weapons also • Depleted uranium is used to protect tanks

  7. Hazardous effects to the environment, animals, and humans • Contaminates river systems and ground water by the radioactive uranium dissolving into it • The radioactive dust moves which goes in water, in plants, into animals and humans • If it can go into us humans, we can get damage in our lungs, kidneys, bones, and many other places. Eventually, this will lead to diseases like cancer or leukemia • The uranium can leave tailings which pollute the air or water and then get into animals or humans

  8. Interesting facts Did you know…? • … that the fist atomic bomb used in warfare was an uranium bomb?!?! • … that the world production of uranium is 35,000 tons (35,0000,000 kg)?!?! • … that only one ton of natural uranium can make more than 40 million kilowatt-hours of electricity?!?! That’s equal as to burning 16,000 tons of coal or as equal to burning 80,000 barrels of oil!!!!!!! • … that uranium that is the size of a gallon milk jug weighs over 150 lbs (about 60 kg)?!?!

  9. More random facts • Uranium has 92 protons and 146 neutrons in the nucleus • Is ranked 48th for most abundant element in natural crustal rock • Acids can dissolve uranium • When uranium is exposed to air, the uranium becomes coated with a layer of oxide • Uranium compounds are highly toxic. So be careful.
