The Element: Chlorine General Information We researched the chemical element known as chlorine. Chlorine has an atomic number of 17 and an atomic weight of 35.453. It has a valence number of 3. The element has 3 energy levels. Chlorine exists as a greenish-yellow gas at normal temperatures and pressures. Chlorine is second in reactivity only to fluorine among the halogen elements. Chlorine is a nonmetal. It is estimated that 0.045% of the earth’s crust and 1.9% of sea water are chlorine.

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 by

Tin is a chemical element with the symbol Sn from the Latin word “stannum.” Its atomic number is 50 and its atomic mass is 118.71. Tin is classified in the ’Other Metals’ section which can be located in groups 13‚ 14‚ and 15 of the Periodic Table. All of these elements are solid‚ have a relatively high density and are opaque. This silvery‚ ductile metal is not easily oxidized in air and resists corrosion. Tin is usually malleable‚ but when cooled it is very brittle. It is found in many alloys
