Many elements have a common valence related to their position in the periodic table, and nowadays this is rationalised by the octet rule.The Greek/Latin numeral prefixes (mono-/uni-, di-/bi-, tri-/ter-, and so on) are used to describe ions in the charge states 1, 2, 3, and so on, respectively. Variable valency: “When an element has more than one valency, its valency is called variable valency.” Copper exhibit valency ‘1’ and ‘2’ i.e. It means by valency we can know how the atoms of an element will combine with atoms of another element.
