Iron is a ubiquitous, magnetic transition metal essential for structural materials and biological oxygen transport in hemoglobin.
Properties of Iron | It forms multiple oxidation states Fe2+, Fe3+, is ductile in metallic form and readily corrodes to form oxides unless protected.
Uses of Iron | Iron ores hematite, magnetite supply steel production, cast iron, tools, machinery and are foundational to modern infrastructure.
Isotopes of Iron | Stable isotopes include Fe 54, Fe 56; iron is essential nutritionally but excess iron is toxic and industrial dusts require exposure controls.
