Chlorine (from the Greek language χλωρóς chloros, meaning "pale green"), is the chemical element with atomic number 17 and symbol Cl. It is a halogen, found in the periodic table in group 17. As the chloride ion, which is part of common salt and other compounds, it is abundant in nature and necessary to most forms of life, including humans. As chlorine gas, it is greenish yellow, is two and one half times as heavy as air, has an intensely disagreeable suffocating odor, and is exceedingly poisonous. In its liquid and solid form it is a powerful oxidizing, bleaching, and disinfecting agent.
Notable characteristics
The pure chemical element has the physical form of a diatomic yellow-green gas, Cl2. Chlorine combines readily with nearly all other elements. At 10 °C one litre of water dissolves 3.10 litres of chlorine and at 30 °C only 1.77 litres.
This element is a member of the salt-forming halogen series and is extracted from chlorides through oxidation and more commonly, by electrolysis.
