Iron

Name: Iron Group in periodic table: 8 es.org/iron http://www.chemicalelements.com/elements/fe.html The actual discovery of iron was probably made so early in the history of the human race that it cannot now be accurately placed. The Bible ascribes the discovery of working iron to Tubal-Cain. The Egyptians ascribe it to one of their early l kings, Hephaestus, who has been identified by students with the Hephaestus of Greek and the Vulcan of Roman mythology. The Egyptians and the Assyrians made iron at a very early period of their history. In ancient tombs and ruins but recently unearthed, many implements of iron are found, cooking utensils, and weapons of various kinds. The Chalybes, a Scythian tribe living south and east of the Black Sea, who attained great skill in iron working, are accredited by ancient writers with being the first to use coal in their furnaces, the inventors of steel or hardened iron, and the discoverers of magnetic iron. The books of Moses mention the use of iron some eleven centuries before the Christian 'era, and the Arundelian marbles fix a date for it before 1370 B. C. Today we use iron in many ways like iron studs for building house its alot stronger then regural nails and helps the house stay stronger. Temperatures Melting point [/K]: 1811 [or 1538 °C (2800 °F)] Boiling point [/K]: 3134 [or 2861 °C (5182 °F)] (liquid range: 1323 K) Critical temperature [/K]: no data compounds: Iron forms such compounds as oxides, hydroxides, halides, acetates, carbonates, sulfides, nitrates, sulfates, and a number of complex ions. It 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. Ferrous sulfate heptahydrate, FeSO4·7H2O, sometimes called green vitriol, is a compound formed by the reaction of dilute sulfuric acid (formerly called oil of vitriol) with metallic iron; it is used in the manufacture of ink, in dyeing, and as a disinfectant. Ferric chloride hexahydrate, FeCl3·6H2O, is a yellow-brown crystalline compound used as a [|mordant] in dyeing and as an etching compound. Ferric oxide, Fe2O3, is a reddish-brown powder used as a paint pigment and in abrasive rouges. Prussian blue, KFe2(CN)6, is a pigment containing the ferrocyanide complex ion. Iron rusts readily in moist air, forming a complex mixture of compounds that is mostly a ferrous-ferric oxide with the composition Fe3O4.======
