  • Discovery of Uranium Fissionability: Until 1938, Otto Hahn and Fritz Strassman had discovered that it could be split of release and that is fission. 
  • Radioactive: It’s being found out that it’s radioactive in 1896 by Henri Antoine Becquerel.
  • Name: This element is named after the planet Uranus, discovered 8 years before in 1781.
  • Price: The price had increase through years, from approximately $10.75/pound (2003), to approximately $45.00/pound (2006), to $100.00/pound (2007) as the highest point and it drop down very fast and then go down slowly. (Graph below)
  • Used as Nuclear and bombs: Uranium is used as nuclear power plant and high-density penetrating bombs. The power one kiligram of Uranium is equal to 3000 tones of coal.

  • Uranium is important for making bombs.
  • Uranium is also important for making electricity (nuclear power) and radioisotopes.
    • Radioisotopes is important for medicine, preservation of food, growing crops and breeding livestock, industrially and smoke detectors

    • ]]>     2017-10-15 07:04:36 UTC https://padlet.com/amber_cheng/uranium/wish/197084011     Concern of Uranium amber_cheng https://padlet.com/amber_cheng/uranium/wish/197207087
  • Human Health effect 
    • If there are high levels of Uranium from any source, including drinking water, people’s risk of kidney damage will increase, because kidney is the most sensitive organ damage by uranium. (Picture bellow, bad kidney)
  • Living thing impact:
    • Radiological Toxicity, Chemical Toxicity, and compound solubility and Route of exposure will impact any living things.
  • Radioactive effect to the environment:
    • The radioactive is very reactive, and air exist as dust that fall into the surface of water, on plants or on places through rainfall.

  • Uranium are related to Plutonium, Americium, actinium, Curium, Neptunium, Lawrencium, Berkelium, Californium, Einsteinium, Fermium, and Mendelevium because they are all classify as actinide metal. Uranium are nearly the beginning of the actinide family, and actinide family consists the element with atomic number from 89 through 103.
  • Uranium are related to Rhodium, Erbium, Lithium, Rhenium, Iridium, Platinum, Scandium, Terbium, Lutetium, Silver, Sodium, Nickel, Strontium, Aluminium, and Lanthanum because they are all Silvery-White.
  • Uranium is related to lead because it can transform to lead.
  • Uranium is related to Plutonium because Uranium can turn into Plutonium by neutron absorption.
  • Uranium is related to thorium because they are both used for Nuclear power.
  • Uranium is related to mercury (Hg), cadmium (Cd), arsenic (As), chromium (Cr), thallium (Tl), and lead (Pb) because they are all toxic heavy metal that have high density and is poisonous/toxic at low concentrations.
