Covalency of Chlorine
A chlorine atom has 7 electrons in its outermost shell, so it can share its 1 electron with one electron of another atom to achieve the 8-electron inert gas electron arrangement.Since one chlorine atom shares 1 electron to achieve the nearest inert gas electron arrangement, therefore,the covalency (or just valency)of chlorine is 1.For example,in the formation of a chlorine molecule, ,each chlorine atom shares its 1 electron with the other atom, so the valency of chlorine in molecule is 1.
