  • U And The Atomic Mass Of Uranium
    406 words
    Uranium Uranium was discovered in the 1700's in the coal mines of bohemia and Jachlovikna. Uranium's atomic number is 92, its Symbol is U and the atomic mass of uranium is 238.0289. Miners called it Pechblende meaning, Pechblende, from the German words p ech, which means either pitch or bad luck, and blende, meaning mineral Uranium's first full analysis was done on 1789 by Martin Klaproth, a self-taught well educated german chemist. Klaproth, having extracted from pitchblende what he called 'a s...
  • Uranium Ores
    599 words
    Uranium was discovered by Martin Heinrich Klaproth, a German chemist, in the mineral pitchblende (primarily a mix of uranium oxides) in 1789. Klaproth, as well as the rest of the scientific community, believed that the substance he extracted from pitchblende was pure uranium, it was actually uranium dioxide (UO 2). After noticing that 'pure' uranium reacted oddly with uranium tetrachloride (UCl 4), Radioactivity was first discovered in 1896 when Antoine Henri Becquerel, a French physicist, detec...
  • Nucleus Of The Plutonium Atom
    916 words
    Plutonium Plutonium is a radioactive metallic element. Although it is occasionally found in nature, mostly all of our plutonium is produced artificially in a lab. The official chemical symbol for plutonium is Pu, coming from its first and third letters. Its atomic number is ninety-four. Plutonium is able to maintain its solid state until very high temperatures, melting at six hundred and forty degrees Celsius, and boiling at three thousand four hundred and sixty degrees. The density of Plutonium...

  • Uranium For Power
    402 words
    Thousands of years ago human beings learned to make fire. By collecting and burning wood they were able to warm themselves, cook food, and manufacture primitive tools. Later, the Egyptians discovered the principal of the sail. Even more recent was the invention of the water wheel. All of these activities utilize various forms of energy-biological, chemical, solar, and hydraulic. Energy, the ability to do work, is essential for meeting basic human needs, extending the life expectancy, and providi...
  • Its Use Of Depleted Uranium
    3,708 words
    I cannot help but give you a brief synopsis of the element uranium, for I am thoroughly outdone by the Discovery Channel's online resource web Their article on uranium is impeccable with the in depth research of a good research paper, but the coherence and simplicity that a sixth grader should have no problem understanding it. Articles and information from Discovery, military and defense, military enthusiasts, and corporation sites are presented relatively unedited to preserve the intended tones...
  • Principal Use Of Uranium
    1,333 words
    Background Uranium is a hard, dense, malleable, ductile, silver-white element that has a symbol of U and atomic number of 92. It is chemically radioactive metallic element. Uranium is a member of the actinide series in group b of the periodic table. It melts at about 1132 X C, boils at about 3818 X C, and has a specific gravity of 19.05 at 25 X C. Uranium is very dense and at about 19 grams per cubic centimeter, it is 1.6 times more dense than lead. The atomic weight of the element is 238.03. It...
