Valency is the combining capacity of the atom of an element. It is equal to the number of electrons an atom can donate or accept or share.

Copper and iron shows more than one valency which is also known as VARIABLE valency.

Therefore, copper shows valencies 1 and 2 :

CU+, cuprous.. And Cu2+,cupric

Iron also shows two valencies:

FE2+,FERROUS.. And Fe3+ ferric
