Major Toxic Waste Sites in Texas When thinking about the most polluted states in our country‚ California and New York instantly pop into our mind. What most people don’t know‚ however‚ is that Texas now ranks number one in most categories of pollution. Whether it be increased emissions from refineries in Beaumont‚ large pits filled with contamination at Kelley Air Force Base‚ or polluted water at Lake Sam Rayburn‚ Texas has more than its fair share of toxic waste. Exxon/Mobil‚ one of the nation’s

atom of an element determines the atom’s ‚ and the number of electrons determines of an element. 3. The atomic number tells you the number of in one atom of an element. It also tells you the number of in a neutral atom of that element. The atomic number gives the “identity “ of an element as well as its location on the Periodic Table. No two different elements will have the atomic number. 4. The of an element is the average mass of an element ’s naturally

Transuranic Elements and their Production Transuranic elements are elements that have an atomic number greater than 92. Transuranic elements have been synthesised in nuclear reactors or in high-energy particle accelerators. Neptunium and plutonium were the first transuranic elements to be synthesised in 1940 by Glenn Seaborg’s research team in the USA. Uranium 238 is bombarded with neutrons produced by the nuclear fission of U-235. Initially an isotope of uranium (U-239) forms which decays

Each work of art has elements of unity and elements of variety. Variety balances out unity and keeps things interesting. The center of interest or focal point is the place the artist draws your eyes first. Artists use balance in order to construct paintings. These elements of art such as unity‚ variety‚ focal point or area of interest and balance will be used to give you a better understanding. Examples from "Giorgio de Chirico" (The Mystery and Melancholy of a Street‚ 1914)‚ "Pablo Picasso" (Seated
