Most of this iron is found in various iron oxides, such as the minerals hematite, magnetite, and taconite. Iron is also the most abundant (by mass, 34.6%) element making up the Earth the concentration of iron in the various layers of the Earth ranges from high at the inner core to about 5% in the outer crust. Iron is believed to be the tenth most abundant element in the universe. Steel is the best known alloy of iron, and some of the forms that iron takes include: pig iron, cast iron, carbon steel, wrought iron, alloy steels, iron oxides. Its applications go from food containers to family cars, from scredrivers to washing machines, from cargo ships to paper staples. Thanks to the combination of low cost and high strength it is indispensable. Iron is the most used of all the metals, including 95 % of all the metal tonnage produced worldwide.
FE ELEMENT SERIES
Iron is chemically active and forms two major series of chemical compounds, the bivalent iron (II), or ferrous, compounds and the trivalent iron (III), or ferric, compounds. Iron rusts in damp air, but not in dry air. It is known to exist in four distinct crystalline forms. Iron is a lustrous, ductile, malleable, silver-gray metal (group VIII of the periodic table).
