Chlorine is second in reactivity only to fluorine among the halogen elements chlorine is a nonmetal it is estimated that 0045% of the earth's crust and 19% of sea water are chlorine chlorine combines with metals and nonmetals and organic materials to form hundreds of chlorine compounds [tags: essays research. 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 35453 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. Known collectively by a term derived from a greek word meaning salt-producing, the halogen family consists of five elements: fluorine, chlorine, bromine, iodine the reason for this, as discussed in the chemical bonding essay, is that most elements bond in such a way that they develop a valence shell of eight electrons. Essay chlorine chlorine is (at room temperature) a greenish-yellow gas that can be readily liquefied at 5170 tarr or 68 atmospheres, at 20 c (68 f), and has a very disagreeable odor its element symbol is cl, atomic number is 17, and atomic mass is 35453 chlorines melting point is -101 c or 1498 f the boiling point. Davy's earliest published work (“an essay on heat, light, and the combinations of light,” in contributions to physical and medical knowledge, principally from the among his many accomplishments davy discovered several new elements it contained only hydrogen and one other element, chlorine. Read this full essay on the element lead lead, whose chemical symbol is pb , is an element that belongs to the carbon family on the periodic table 478 words - 2 pages chlorine chlorine is (at room temperature) a greenish-yellow gas that can be readily liquefied at 5170 tarr or 68 atmospheres, at 20 c (68 f), and.
Chlorine protects organisms ranging from the ecuadorian tree frog, to wood rotting fungi chlorine is also surprisingly more plentiful than carbon believe it or not chlorine was the first substance used as a poisonous gas in world war i chlorine, symbol cl, is a greenish-yellow gaseous element in the group 17 of the. Chlorine, as chlorine has fewer electrons shells than bromine as a result, chlorine is smaller and has a smaller atomic radius the difference. While chemical symbols always begin with a capital letter, the names of chemical elements do not in running text, you should be writing hydrogen, oxygen, chlorine, iron, etc.
Chlorine, for example, is more electronegative than bromine, which is more electronegative than iodine oxygen is more electronegative than nitrogen, which is more electronegative than carbon fluorine is the most electronegative element, with oxygen following in second place carbon and hydrogen. Since fluorine is the most chemically active of the nonmetallic elements, it combines directly with most elements and indirectly with chlorine, nitrogen, and oxygen fluorine occurs naturally in the combined form as apatite, cryolite, and fluorite favourite, from which most fluorine compounds are derived, is usually mined in.
