'''Chlorine''' is in Group 7 of the [[periodic table]], making it a [[halogen]] along with such elements as [[fluorine]], [[bromine]] and [[iodine]]. It has an [[atomic number]] of 17. Like other halogens, it is reactive to most [[metal]]s and is never found free in nature. The chlorine [[molecule]] (Cl<sub>2</sub>) contains two chlorine [[atom]]s bonded together.
==Compounds==
Compounds of chlorine are called chlorides. Common chlorides include:
* Ammonium chloride, NH<sub>4</sub>Cl
* Calcium chloride, CaCl<sub>2</sub>
* Lithium chloride, LiCl
* Potassium chloride, KCl
* Sodium chloride, NaCl
==Uses==
The primary use of chlorine is in the production of various plastics and artificial fibers, such as [[polyvinyl chloride]]. Chlorine is also used as a disinfectant for public water supplies and is an important component of several pharmaceuticals. Chlorine can also bond with an oxygen atom to form sodium hypochlorite (NaClO) which acts as a bleach.<ref>http://www.eurochlor.org/products</ref>
