Isotope

Element project (Br) Whats bromine? bromine (Br) is a deep red, noxious liquid, and a member of the halogen elements, or Group 17 group vlla of the periodic table. It has an atomic number of 35. What you will soon find out by my paper is how it's used in everyday life, how it's produced and its physical properties. Bromine was discovered in 1826 by the French chemist Antoine-Jérôme Balard in the residues from the manufacture of sea salt at Montpellier. He liberated the element by passing…

The periodic table had been a key factor in many ways to finding new elements, like scandium, silicon, and neon. It has shown new ways those elements could help us by predicting certain elements reactions. While Dimitri Ivanovich Mendeleev is considered to be the creator of the periodic table, there were many contributions that helped the creation of the useful graph be achieved. Between 1817 and 1829 Johann Dobereiner was grouping elements with similar properties into groups of threes,…

researching in such topics, when fission was discovered during 1938, with this discovery scientist were able to tell that certain radioactive components could combine and form a lethal bomb. The United States the isotopes uranium-235 and plutonium-239, the reaction of this two isotopes they cause a chain reaction. According to The Columbia Encyclopedia 6th edition (n.d.)’’If the mass of the fissionable material exceeds the critical mass (a few pounds), the chain reaction multiplies rapidly into…

unknown element and purify it, proving Mendeleev’s predictions. The element would be named Germanium after Germany. Structure. Germanium is found naturally in five different forms of isotopes. The most stable isotope, 72Germanium, is composed of 32 Protons, 32 Electrons, and 40 Neutrons. However, the most common isotope is…

Within the past fifty years of human intervention, carbon dioxide concentration levels have nearly doubled. So what is the big deal? Humans still exist, the air is still breathable, and mortality rates have never been higher. Mark Bowen is a physicist from Massachusetts Institute of Technology. He wrote his book Thin Ice in 2003 to explain the science of global warming. Bowen was part of the Ice Core Paleoclimatology Research Group lead by Lonnie Thompson, a leading paleoclimatologist, to drill…

Eighteen-thousand people lost their lives on March 11th, 2011 due to the triple disaster in Japan. An earthquake, tsunami, and three meltdowns caused the explosion of a nuclear power plant in Japan. The event was tragic, and out of the control of the workers at Fukushima Daiichi power. Despite certain exposure to radiation fifty brave and selfless workers stayed behind in efforts to control the devastating situation, and seven-hundred and fifty workers were evacuated. In addition to the 50…

Tom Reimchen of the University of Victoria, tracked uptake of nitrogen from salmon in coastal forests. They did this by following the nitrogen isotope 15, which is found almost exclusively in marine environments. It turns out that the great trees of coastal temperate rainforests—such as Douglas fir, Sitka spruce, western hemlock and western red cedar—owe a good deal of their girth to the tsunami…

Lithium is very abundant, it is a soft silver white alkali metal with the atomic number of three. Lithium is silver and contains no odor (Element Project). In addition to those features, lithium has a total of seven isotopes, two natural and five unnatural. The two natural occurring isotopes are 6Li (7.59% abundance) and 7Li (92.41% abundance) both are stable as well as radioactive (Chemicool Web). Lithium being…

The isotopes that reacts are U-235 and U-238. The nucleus of the isotope U-235 is unstable and reacts easily. If anyone would go to a nuclear power plant, they will see that majority of the uranian there is U-238. The plants use the process of fission, which is the splitting of atoms of uranium…

(Atomic Archive) (Energy.gov) Uranium isotope separation facilities are built at Oak Ridge, Tennessee; plutonium production reactors are built at Hanford, Washington; and a weapons laboratory is set up at Los Alamos, New Mexico. (Atomic Archive) (Energy.gov) A microscopic sample of pure plutonium…
