    Uses of Iron Uses Of

    Iron is a metallic chemical element that is very common in our planet. It has many uses in different industries and even in the human body. Iron has a chemical symbol of Fe. It is in a category of transition elements and is rarely found in pure form. Iron gets oxidized when it comes in contact with atmospheric oxygen. That’s why most of its ores that you can find in the surface of the earth
