The halogens make up Group VIIA of the Periodic Table of the elements. Elemental halogens are diatomic molecules. However, due to their high reactivity, the halogens are never found in nature in native form. The family name means "salt-forming," from the Greek for salt, halos, and for ...
The halogens or halogen elements are a series of nonmetal elements from Group 17 IUPAC Style (formerly: VII, VIIA) of the periodic table, comprising of fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). Since Astatine (At) is a radioactive element, halogens ...
