Overview
Chlorine is a greenish yellow gas at room temperature that forms salts and organic chlorinated compounds.
Properties
It is highly reactive, strongly oxidizing and forms stable chloride ions in aqueous environments.
Occurrence and Uses
Produced industrially by electrolysis of brine, chlorine is used for water disinfection, PVC production and chemical synthesis.
Isotopes and Safety
Stable isotopes Cl 35 and Cl 37 exist; elemental chlorine is toxic and corrosive and requires strict industrial safety measures.
