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 metals and is never found free in nature. The chlorine molecule (Cl2) contains two chlorine atoms bonded together.
Compounds
Compounds of chlorine are called chlorides. Common chlorides include:
- Ammonium chloride
- Calcium chloride
- Lithium chloride
- Potassium chloride
- Sodium chloride
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, which acts as a bleach.[1]
