Iron - Georgia State University

Pure iron is a bright silvery-white metal which oxidizes (rusts) rapidly in moist air or in water containing dissolved oxygen. It is soft, malleable, and ductile, and is strongly magnetic (ferromagnetic).It is rare to find it in elemental form on the Earth, but the sample at right was found in Greenland. It has also been found in igneous rocks in Russia.
