The halogens are five non-metallic elements found in group 17 of the periodic table. The term "halogen" means "salt-former" and compounds containing halogens are called "salts". All halogens have 7 electrons in their outer shells, giving them an oxidation number of -1. The halogens exist, at room temperature, in all three states of matter:

*Solid- Iodine, Astatine

*Liquid- Bromine

*Gas- Fluorine, Chlorine

The Halogens are:

*Fluorine

*Chlorine

*Bromine

*Iodine

*Astatine
