Elements Having Variable Valency Valency of cupric which is valency of Cuprous or cuprous valency (Cu+2) and cupric (Cu+3) are two types of copper (Cu). Iron (Fe) is divided into two types: ferrous (Fe+2) and ferric (Fe+3).
Then in 1869, as a result of an extensive correlation of the properties and the atomic weights of the elements, with special attention tovalency(that is, the number of single bonds the element can form), Mendeleev proposed the periodic law, by which “the elements arranged according to the ...
