Halogens: Properties, Characteristics, and Common Elements (F, Cl, Br, I)
Fluorine, chlorine, bromine, and iodine are called halogens.
The term "halogen" comes from the Greek words "hals" (salt) and "genos" (born), because these elements are found in salts. They are a group of non-metallic elements in the periodic table that share similar chemical properties.
