Name : Iron Symbol : Fe Atomic # : 26 Atom weight: 55.847 Melting P. : 1535 Boiling P. : 2750 Oxidation : +2, +3 Pronounced : EYE-ern From : Name from Anglo-Saxon, iron; Symbol from Latin ferrum, iron Identified : Identified and used since prehistoric times Appearance : Malleable, ductile, silvery-white metal Note : The fourth most abundant element in earth's crust [Properties] Iron is generally described as a moderately heavy, hard, malleable, and ductile metal. In its pure form, it has a silvery-white color. One of the most distinctive features is its ability to take and retain a magnetic field. Iron is one of the Group-VII transition metals. These metals have two incomplete electron shells. Iron has four allotropic forms. The alpha form is the most familiar because it is the one that exists at room temperature. As the temperature rises above 770 degrees, the beta form emerges. The most critical feature of this particular transition is that the iron loses its magnetic properties. Transitions to the gamma and delta forms take places at 928 and 1530 degrees, respectively.
