Periodic element cl2/13/2024 Video: Chlorine Electron Configuration Notation. In fact, chlorine was used as a war gas in 1915.Įxposure to chlorine should not exceed 0.5 ppm (8-hour time-weighted average - 40 hour week). Therefore the Chlorine electron configuration will be 1s22s22p63s23p5. As little as 3.5 ppm can be detected as an odor, and 1000 ppm is likely to be fatal after a few deep breaths. ![]() The gas irritates the mucus membranes and the liquid burns the skin. HandlingĬhlorine is a respiratory irritant. Much chlorine is used to sterilize water and wastes, and the substance is employed either directly or indirectly as a bleaching agent for paper. Organic chemistry demands much from chlorine, both as an oxidizing agent and in substitution, since it often brings many desired properties in an organic compound when substituted for hydrogen, as in one form of synthetic rubber. Chlorine, chemical element of the halogen group that is a toxic, corrosive, greenish yellow gas, irritating to the eyes and respiratory system. Further use is in the manufacture of chlorates, chloroform, carbon tetrachloride, and in the extraction of bromine. Most of the chlorine produced is used in the manufacture of chlorinated compounds for sanitation, pulp bleaching, disinfectants, and textile processing. Chlorine, atomic symbol Cl, has an atomic number of 17 and lies in group 17, the halogen group, of the periodic table. The table is divided into rows (periods) and columns. In the periodic table of elements, all known chemical elements are arranged according to increasing nuclear charge (atomic number). Element lists, scales and much more free, free and open source. It is also extensively used in the production of paper products, dyestuffs, textiles, petroleum products, medicines, antiseptics, insecticides, food, solvents, paints, plastics, and many other consumer products. Interactive periodic table with atomic, chemical and physical properties of all known elements. Even the smallest water supplies are now usually chlorinated. ![]() It is used for producing safe drinking water the world over. UsesĬhlorine is widely used in making many everyday products. At 10☌ one volume of water dissolves 3.10 volumes of chlorine, at 30☌ only 1.77 volumes. At 10C one volume of water dissolves 3.10 volumes of chlorine, at 30C only 1.77 volumes. It is a member of the halogen (salt-forming) group of elements and is obtained from chlorides by the action of oxidizing agents and more often by electrolysis it is a greenish-yellow gas, combining directly with nearly all elements. It is a member of the halogen (salt-forming) group of elements and is obtained from chlorides by the action of oxidizing agents and more often by electrolysis it is a greenish-yellow gas, combining directly with nearly all elements. In nature it is found in the combined state only, chiefly with sodium as common salt (NaCl), carnallite, and sylvite. Chlorine was named in 1810 by Davy, who insisted it was an element. Discovered in 1774 by Scheele, who thought it contained oxygen. This chemical, when used in small doses, has no side effects in large doses, however, it is fatal.ħ, 6, 5, 4, 3, 2, 1, −1 (a strongly acidic oxide)įrom the Greek word chloro, greenish yellow. Solid nonmetals are also very brittle.Some tree frogs contain a chlorine compound in their skin that is a very powerful pain killer. A nonmetal is typically dull and a poor conductor of electricity and heat. Metals are also malleable (they can be beaten into thin sheets) and ductile (they can be drawn into thin wires). Chlorine is a nonmetal or chemical element of group-17 or halogen family of the periodic table with the symbol Cl and atomic number 17. ![]() A metal is a substance that is shiny, typically (but not always) silvery in color, and an excellent conductor of electricity and heat.
