1: General Idea:
The Basics:
-Atomic Number: 92
-Atomic Mass: 238 amu
-Symbol: U
-Number of Protons: 92
-Number of electrons: 92
-Number of neutrons: 146 -Uranium is one the densest materials known. (19 g/cm3) 1.6 times denser than lead. It also oxidizes at room temperature. If you grind it into a powder, Uranium will spontaneously combust in air at room temperature.
-Physical properties include: -it weighs 238 amu. -it is a solid at room temperature.
-Chemical properties include: -it oxidizes at room temperature. -it is radioactive
2: History:
Uranium was discovered in 1789 (almost 300 years ago) by a German chemist, M. S. Klaproth. It was named in honor of the planet Uranus, which had just been discovered only 8 years before. A French scientist, Henri Becquerel, discovered that uranium had a radioactive property in 1896. In 1938, Otto Hahn showed that if you bombard a uranium atom with a high speed neutron, it fissions into isotopes of smaller, lighter elements. When that atom fissions, it releases all of the energy holding it together. In 1939, it was suggested that when uranium nuclei are split from a neutron, other neutrons might be released to cause a self-sustaining fission reaction. This was confirmed by F. Joliot. In 1942, the first self-sustaining nuclear chain reaction was achieved by Fermi and a team of scientists in a pile of 400 tons of graphite, 6 tons of uranium metal, and 58 tons of uranium oxide at the University of Chicago. It was tested to make a bomb in Alamogordo, New Mexico on July 16, 1945. It was put into action to end WWII on August 6, 1945 at Hiroshima.
3: Uses:
Uranium is the most efficient and most popular form of nuclear energy. Uranium is made into rods and is shown below.
4: Glossary:
A:
-Atomic Mass: the mass of an isotope of an element in atomic mass units.
-amu- Atomic Mass Units.
-Atomic number: number of protons in an atomic nucleus; it indicates the position of an element in the periodic table.
C:
-Chemical properties: a property or characteristic of a substance that is observed during a reaction in which the chemical composition or identity of the substance is changed.
-Combust: to burn.
E:
-Electron: A sub atomic particle with a negative charge and a very small mass.
F:
-Fission: the splitting of the nucleus of an atom into nuclei of lighter atoms, accompanied by the release of energy.
I:
-Isotope: any of two or more forms of a chemical element, having the same number of protons in the nucleus, or the same atomic number, but having different numbers of neutrons in the nucleus, or different atomic weights.
N:
-Neutron: a sub atomic particle having no charge, mass slightly greater than that of a proton.
-Nuclei: Plural for nucleus.
O: -Oxidize: to cover with a coating of oxide or rust.
P:
-Periodic
nuclear plants are expected to increase by 40% to 110%. More nuclear plants will have more uranium requirement. 60% of the world uranium is reserved in 4 countries.Following table shows the distribution of uranium globally S. No. Country Uranium Reserve 1 Australia 31% 2 Kazakhstan 12% 3 Russia 9% 4 Canada 9% New Developing market for uranium Australia exports its uranium to many countries like: USA, South Korea, Canada, Japan, Russia, China, Taiwan, European Union…
2014 Uranium mining on Mount Taylor? There should be no mining done on Mount Taylor because of health issues, environmental problems, and tribal problems. Today many people have been affected by uranium mining, from health problems to environmental problems. All these things have a big impact on the environment and its people. Uranium mining has been proven to cause a range of health problems to the people surrounding the area of the uranium mining sites. The waste from the uranium mining sites…

with her sister. She would work to support Bronya while she was in school and Bronya would return the favor after she completed her studies. For roughly five years, Curie worked as a tutor and a governess. She used her spare time to study, reading about physics, chemistry and math. In 1891, Curie finally made her way to Paris where she enrolled at the Sorbonne. She threw herself into her studies, but this dedication had a personal cost. With little money, she found a cheap rental in a Paris attic…
power plants that supply about 16 percent of the world's electricity. There are currently 104 operating U.S. nuclear power plants that produce over 20 percent of U.S. electricity. ADVANTAGES a) Nuclear power generation does emit relatively low amounts of carbon dioxide (CO2). The emissions of green house gases and therefore the contribution of nuclear power plants to global warming is therefore relatively little. . USA is currently responsible for a quarter of all carbon dioxide emissions…
Chernobyl By Landon Chernobyl is a name you've probably heard more than once in your lifetime. It’s known as the worst nuclear disaster of all time. What was a simple backup power energy check turned into a complete nuclear meltdown and caused people to evacuate their homes, thousands of radiation related deaths, and 1000 sq miles of uninhabitable land for the next 100,000 years. Chernobyl is a nuclear power plant 10 km north of the Ukrainian capital Kiev. It housed 4 very large nuclear…
Energy supplies about 17% of the world's electricity (1). Nuclear energy is either produced by "nuclear fission" in whereas nuclei are split to release energy. It may also be produced by "nuclear fusion" whereas small nuclei are combined to release energy (1). The atomic bomb and nuclear reactors in nuclear plants work on the principle of nuclear fission, where the element uranium is used to undergo fission (Mathis,2). I found that for a nuclear power plant to work, the uranium being employed must…
Fossil Fuels. There are five fossil fuels identified as Oil, Coal, Natural Gas, Oil Sands and Uranium. Oil, coal, natural gas and oil sands are all created from millions of years of rock and sediment pressure, heat and particles of once living creatures or plant forms, because of this long delay of creation it is not a reliable source of energy seeing in as soon as it is used up it cannot be re-created. Uranium, one of the more abundant fossil fuels can be found in a wide range of rocks, soils and occasionally…
The final step in processing separates the glycerol from the mixture and leaves a biodiesel that's ready to be used as fuel. Solar panels are nothing new; we have all seen them drilled into the roofs of our neighbor’s houses and possibly even thought about getting some ourselves but decided no, it’s too much work. But what about instead of installing solar panels on your roof—you just give your house a new paint job? Of course you’d have to be sure to use solar paint. That’s right, solar paint…
