The halogens are located on the left of the noble gases on the periodic table. These five toxic, non-metallic elements make up Group 17 of the periodic table and consist of: fluorine (F), …

The halogens are the family of chemical elements that includes fluorine (atomic symbol F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). The halogens make up Group VIIA of …

The word ‘halogen’ is derived from Greek and originally means “salt-forming“. Halogens are found in the environment only in the form of ions or compounds because of their high reactivity.

The halogens, aka halogen family, are a group of reactive elements in group 17 of the periodic table, to the right of the chalcogens, and to the left of the noble gases.

Halogens are highly reactive, especially with alkali metals and alkaline earths. Halogens are extremely active chemically. Chemical activity increases as you move upward in the group, …

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 origin of halogen is the Greek word meaning the production of salt by direct reaction with a metal. Since their reactivity is very high, halogens are found in nature only as compounds.
