Iron, also called ferrum, is a chemical element originated from the Anglo-Saxon name iren (ferrum in Latin). It was early used before 5000 BC. “Fe” is the canonical chemical symbol of iron. Its atomic number in the periodic table of elements is 26 with location at Period 4 and Group 8, belonging to the d-block. The relative atomic mass of iron is 55.845(2) Dalton, the number in the brackets indicating the uncertainty.
Iron also has biological importance as it is responsible for carrying oxygen in blood. It is evaporated under vacuum to form layers in the production of semiconductors, magnetic storage media, and fuel cells, just to name a few.
