Americium

The Toilet Yes...those tales you've heard are true. The toilet was first patented in England in 1775, invented by one Thomas Crapper, but the extraordinary automatic device called the flush toilet has been around for a long time. Leonardo Da Vinci in the 1400's designed one that worked, at least on paper, and Queen Elizabeth I reputably had one in her palace in Richmond in 1556, complete with flushing and overflow pipes, a bowl valve and a drain trap. In all versions, ancient and modern, the working

you by surprise. Americium. Americium was named after where it was created, America. Americium can found in period 7, in the group of the Actinides. The element has an atomic number of 95. American scientists in Glenn T. Seaborg, Ralph A. James, Leon O. Morgan, and Albert Ghiorso created americium in 1944, at the University of Chicago. Bombarding the isotope, Plutonium 239, with neutrons in a nuclear reactor produced americium, which was how it was they identified it. Americium is found to be in

on the periodic table, Americium was recognised in November 1945 by a chemist Glenn Seaborg who discovered the element as well as co-discovering ten other elements including Plutonium.1 The chemical element americium has atomic number 95 and an atomic weight of 243. Americium is a malleable, silvery white metal that tarnishes slowly in dry air at room temperature. . There are several known isotopes of americium and all of them are radioactive, the most stable being Americium -243 with a half-life

Chemical process in making americium: The most popular type of smoke alarm is an ionization chamber smoke alarm. These contain 0.28 micrograms of the radioactive isotope americium 241, in the form of americium dioxide. Americium is a synthetic element, so it must be produced in a nuclear reactor. Americium is made from plutonium 241, yet this needs to also be made in a nuclear reactor. Uranium 238 in a nuclear reactor it is hit with a neutron, which makes uranium 239. Uranium 239 has a half-life

Apoorav Joshi Mr. Yagar Chemistry 10C 12/7/2015 The Newest Elements There have been many elements that have been discovered in this world. The two latest elements that have been discovered are ununquadium and ununhexium. Ununquadium is element number 114 on the periodic table. It was given the official name of flerovium by the IUPAC in 2012. Ununhexium is element 116 on the periodic table. It was given the official name of livermorium by the IUPAC in 2012. There are two other elements that have

Nuclear energy holds great interest for those looking for a sustainable energy source. Our current energy requirements are met by the use of fossil fuels. However, there exist some substantial problems with fossil fuels. Not only are they limited, but they also contribute to the carbon dioxide emissions and thus to global warming. Use of nuclear energy will cut the percentage of carbon emission as it does not involve any burning. Instead, the splitting of nuclei of atoms provides the energy. Using

The primary concern when disposing of nuclear waste and cleaning the facilities that produce it is the duration of half-lives of the elements that make up nuclear waste. One example is Uranium-235, which is used widely by nations that have a nuclear weapons program. U-235 has a half-life of 703,800,000 years. This means that U-235 will take over 700 million years for it to decompose by half. It is estimated that these elements will still be hazardous for ten times their half-lives. At this rate

Introduction In the "Radioactive Boy Scout" the author tells us about David Hahn, a teenage boy who tries to build a homemade breeder nuclear reactor in 1994, at the age of 17. He was a scout in the Boy Scouts of America, and secretly conducted experiments in a backyard shed at his mother 's house in Clinton Township, Michigan. Even though the radioactivity given off by his reactor never reached a dangerous state, when he was stopped by the police for another reason they found materials in his vehicle

chlorine, ammonia, Americium-241, or Cesium-137 to directly or make a device to place toxic or fatal exposure in public or private areas, or place materials with radiation emitting materials in public or private places to cause damage or irreversible harm to the people that live or work there. Short-term exposure to low-level radiation is not harmful though, and many people living in spaces that were built with the International Building Code are exposed to the material Americium-241, which is used

How did Curie’s research/experiment changed the model of the atomic theory? Marie’s experiment and research had a massive impact on the atomic theory by discovering two new elements that have helped prove the existence of atoms and making the theory of it more believable for people. Her discovery had landed her multiply awards such as nobel prizes etc and Marie work in Chemistry will be remembered for a long time by her making a massive impact on science and help make the other scientist take women
