Iron Bohr ModelIron(Fe) atomic and molecular weight, atomic number and elemental symbolIron is a Block D, Group 8, Period 4 element. The number of electrons in each of Iron's shells is 2, 8, 14, 2 and its electron configuration is [Ar] 3d6 4s2. Elemental IronThe iron atom has a radius of and its Van der Waals radius is In its elemental form, CAS 7439-89-6, Iron has a lustrous grayish metallic appearance. Iron is the fourth most common element in the Earth's crust and the most common element by mass forming the planet earth as a whole. Iron is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH) . n(H2O)) or siderite (FeCO3). It is rarely found in its metallic form since it tends to oxidize. Iron was first discovered by Early Man.

Iron and its compounds have numerous uses. It is the most commonly used metal for commercial applications due to its hardness, historical availability, and low cost. Once used on its own, it is now alloyed with carbon, nickel and other elements to produce steel and other high strength, non-corrosive, structural metals. High Purity (99.999%) Iron Oxide (Fe2O3) PowderIron is a primary colorant in glass and ceramics. High Purity (99.999%) Iron (Fe) Sputtering TargetIt is also used as a catalyst. It is the basis for low grade magnets and, because of its magnetic properties, is used in memory tape and magnetic resonance imaging (MRI). Iron is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity). Elemental or metallic forms include pellets, rod, wire and granules for evaporation source material purposes. Iron nanoparticles and nanopowders provide ultra-high surface area which nanotechnology research and recent experiments demonstrate function to create new and unique properties and benefits. Oxides are available in powder and dense pellet form for such uses as optical coating and thin film applications. Oxides tend to be insoluble. Fluorides are another insoluble form for uses in which oxygen is undesirable such as metallurgy, chemical and physical vapor deposition and in some optical coatings. Iron is also available in soluble forms including chlorides, nitrates and acetates. These compounds can be manufactured as solutions at specified stoichiometries.

Iron is not toxic; however, safety data for Iron and its compounds can vary widely depending on the form. For potential hazard information, toxicity, and road, sea and air transportation limitations, such as DOT Hazard Class, DOT Number, EU Number, NFPA Health rating and RTECS Class, please see the specific material or compound referenced in the Products tab below.
