Iron Fe Periodic Table of Elements Coffee Mug, Chemistry Mug, Science Gift, Tea Cup, Element 26. Iron is the most reactive metal of the triad, iron, ruthenium, and osmium. The chapter also discusses the physical properties, chemical reactivity, and group trends of iron, ruthenium, and osmium. Iron, ruthenium, and osmium are lustrous and silvery in color. Pure iron is produced on a relatively small scale by the reduction of pure oxide or hydroxide with hydrogen, or by the carbonyl process in which iron is heated with carbon monoxide under pressure, and the iron pentacarbonyl so formed is decomposed at 250☌ to give the powdered metal. Iron is believed to be the main constituent of the earth's core as well as the major component of “siderite” meteorites. The nuclei of iron are stable and give it a comparatively high cosmic abundance. Ruthenium and osmium are generally found in the metallic state along with other “platinum” and “coinage” metals.
