How many valence electrons do the halogens possess? They attain the octet either by accepting an electron to form a univalent anion, X-, (F-, Cl-, Br- and I-) by sharing the unpaired electron with the unpaired electron of another atom to form a covalent bond (as in Cl2, Br2, HCI, HF etc). In many cases, elements that belong to the same group (vertical column) on the periodic table form ions with the same charge because they have the same number of valence electrons. These elements are fluorine (F), chlorine (Cl), bromine (Br), Iodine (I), astatine (At), and Tennessine (Ts). Why halogens are called halogens? All halogens have 7 valence electrons.
