Valency refers to the number of hydrogen atoms or electrons an element can gain or lose to form compounds. Some elements exhibit variable valency, meaning they can gain or lose different numbers of electrons. Examples given are iron, which can have a valency of 2+ or 3+ , and copper, silver, mercury, tin, lead, phosphorus and sulfur, which all can have more than one possible valency state and the corresponding ion names are modified based on the valency.
