What is the valency of ferrous and ferric ion?

Whether iron is in the ferrous or ferric state depends on the ionic charge of the iron cation, which can either exist in the +2 or +3 oxidation state. Iron is a metal and will therefore take a positive charge. Iron happens to be, more specifically, a transition metal so it can form multiple positive ions. The -ous ending means it is in the lower oxidation state (+2) and the -ic ending means it is in the higher oxidation state (+3).


Why some elements have variable valencies?

Certain elements combine with other atoms, donating, accepting or sharing electrons in different proportions depending on the nature of the reaction. For example, iron combines with oxygen to form ferrous oxide as well as ferric oxide. In the formation of ferrous oxide, iron exhibits a valency of +2, whereas in ferric oxide, it has a valency of +3. This is termed variable valency
