This important group of elements occupies Group VII of the periodic table. Its first element, fluorine, is the most strongly electronegative element known. All halogens are electron defficient and readily share electrons with other elements to staisfy their valency needs, eg. they all form compounds with hydrogen, with the formula HX (where X=halogen)
are the highly reactive elements fluorine, chlorine, bromine, iodine and astatine
