⭐Hey Friend
Certain elements exhibit more than one valency, hence, exhibit variable valencies. For example, cuprous(Cu) and cupric(Cu²), ferrous(Fe²) and ferric(Fe³), etc.
The lower valency of an ion ends with -ic. According to latest IUPAC nomenclature, the valency is written in Roman numbers in brackets after the cations for example, CuCl, i.e., cuprous chloride is written as copper(I) chloride, CuCl2, i.e., cupric chloride is written as copper(II) chloride.
Reason for Variable Valency :- An atom of an element can sometimes lose electrons from the valence shell as well as the penultimate shell. Therefore, such an element exhibit variable valency.
Hope it helps you..!! ❤
