NaCl, sodium chloride or KCl, potassium chloride.

In fact, the name halogen, meaning salt producer, was originally defined for chlorine (in 1811 by J. no, but chlorine (cl) is chloride is the ionic compound of chlorine and a metal found on the periodic table eg. Chlorine reacts directly with nearly all other elements with metals, it forms salts called chlorides. Other compounds of chlorine occur as minerals in the earth's crust, including huge underground deposits of solid sodium chloride.Īlong with fluorine, bromine, iodine and astatine, chlorine is a member of the halogen family of elements in group 17 of the periodic table-the most non-metallic (least metallic) and most highly reactive group of elements. At an average concentration of 0.67 oz (19 g) of chlorine in each liter of sea water, it is estimated that there are some 10 16 tons of chlorine in the world's oceans.

In nature, chlorine is widely distributed over the earth in the form of the salt ( sodium chloride) in sea water. In 1994, more than 24 billion lb (11 billion kg) of chlorine were produced. Chlorine is a yellow-green gas at room temperature. In spite of its disagreeable nature, there are so many everyday products that contain chlorine or are manufactured through the use of chlorine that it is among the top ten chemicals produced in the United States each year. Chlorine is a chemical element with atomic number 17 which means there are 17 protons and 17 electrons in the atomic structure. It was, in fact, one of the first poisonous gases used in warfare-in 1915 during World War I. Ordinary chlorine is a mixture of 75.77% chlorine-35 atoms and 24.23% chlorine-37 atoms.Ĭhlorine is a highly poisonous, greenish yellow gas, about two and a half times as dense as air, and with a strong, sharp, choking odor. In the periodic table, the elements are listed in order of increasing atomic number Z. It is used in swimming pools commonly and also making drinking water safe by killing bacteria. The number of electrons in each element’s electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior. Chlorine disinfection of recreational water for. Infopleases Periodic Table shows the atomic weight, melting and boiling points, density, appearance, and additional properties for each element. Chlorine much like other Halogens has antiseptic properties. Up-to-date, interactive, and detailed information on every chemical element. It has the atomic number 17 in the periodic table and belongs in Group 17, the Halogens. It consists of two stable isotopes, of mass numbers 35 and 37. Interactive periodic table of the chemical elements Properties, history, name origin, facts, applications, isotopes, electronic configuation, crystal structure. Chlorine (Cl) exists as a yellow green gas with a pungent smell. Chlorine is the non-metallic chemical element of atomic number 17, symbol Cl, atomic weight 35.45, melting point -149.8☏ (-101☌), and boiling point -29.02☏ (-33.9☌).
