58Fe0.Iron is a chemical element in the periodic table that has the symbol Fe and atomic number 26.Iron is the most abundant metal, and is believed to be the tenth most abundant element, in the universe.Its symbol Fe is an abbreviation of ferrum, the Latin word for iron.When a star that has sufficient mass to produce iron does so, it can no longer produce energy in its core and a supernova will ensue.Cosmological models with an open universe predict that there will be a phase where as a result of slow fusion and fission reactions, everything will become iron.Contaminants present in pig iron that negatively affect the material properties, such as sulfur and phosphorus, have been reduced to an acceptable level.Wrought iron contains less than 0.Alloy steels contain varying amounts of carbon as well as other metals, such as chromium, vanadium, molybdenum, nickel, tungsten, etc.Iron (III) oxides are used in the production of magnetic storage in computers.By 3000 BC to 2000 BC, increasing numbers of smelted iron objects (distinguishable from meteoric iron by the lack of nickel in the product) appear in Mesopotamia, Anatolia, and Egypt.In The Illiad, weaponry is mosty bronze, but iron ingots are used for trade.By 1600 BC to 1200 BC, iron was used increasingly in the Middle East, but did not supplant the dominant use of bronze.This period of transition, which occurred at different times in different parts of the world, is the ushering in of an age of civilization called the Iron Age.Concurrent with the transition from bronze to iron was the discovery of carburization, which was the process of adding carbon to the irons of the time.This product is strong, can be cast into intricate shapes, but is too brittle to be worked, unless the product is decarburized to remove most of the carbon.Through a good portion of the Middle Ages, in Western Europe, iron was still being made by the working of sponge iron into wrought iron.Early iron smelting (as the process is called) used charcoal as both the heat source and the reducing agent.In a blast furnace, iron ore, carbon in the form of coke, and a flux such as limestone are fed into the top of the furnace, while a blast of heated air is forced into the funace at the bottom.Approximately 1100Mt (million tons) of iron ore was produced in the world
in 2000, with a gross market value of approximately 25 billion US dollars.The 1100Mt of iron ore was used to produce approximately 572Mt of pig iron.This heap of iron ore pellets will be used in steel production.Iron (II) state, Fe2+, previously ferrous

Iron is essential to all organisms, except for a few bacteria.Animals incorporate iron into the heme complex, an essential component of proteins involved in redox reactions, including respiration.For example, when the body is fighting a bacterial infection, the body "hides" iron so it cannot be used by the bacteria (see transferrin).The isotope 56Fe is of particular interest to nuclear scientists as it represents the most stable nucleus possible.It is not possible to perform fission or fusion on 56Fe and still liberate energy.This does not hold true for any other element.Possibly the energy released by the decay of 60Fe contributed, together with the energy released by decay of the radionuclide 26Al, to the remelting and differentiation of asteroids after their formation 4.The abundance of 60Ni present in extraterrestrial material may also provide further insight into the origin of the solar system and its early history.Precautions
Excessive dietary iron is toxic, because excess ferrous iron reacts with peroxides in the body, producing free radicals.The lethal dose of iron in a 2 year old is about 3 grams of iron.Overconsumption of iron is the single highest cause of death in children by unintentional ingestion of pharmaceuticals.If iron intake is excessive a number of iron overload disorders can result, such as hemochromatosis.For this reason, people shouldn't take iron supplements unless they suffer from iron deficiency and have consulted a doctor.Blood donors are at special risk of low iron levels and are often recommended to supplement their iron intake.See also
