Jiho_Compounds+with+Iron

Compounds of iron, for example, are found in almost all living things: iron compounds are a vital nutrient for all animals, and they make our blood appear red in color. Iron compounds are also the basis of a rich variety of natural colors, both in rocks and in nature. Iron, along with very few other elements, possesses the property of magnetism. This property makes iron essential in compasses and inside every electric motor. Indeed, this makes iron one of the most versatile of all the elements.
