The chemical element represented by the symbol Fe is iron. Derived from the Latin word "ferrum," iron is a vital metal known for its strength and abundance in the Earth's crust. It is primarily used in the production of steel, which is an essential material for construction and manufacturing. Iron is also crucial in various biological processes, including the transport of oxygen in the blood through hemoglobin, which is why it is an important nutrient for humans and other living organisms. Iron's unique properties, such as malleability and ductility, make it highly versatile.
