The chemical element with the symbol Fe is iron. Iron is a transition metal that is known for its strength, malleability, and magnetic properties. It has been used by humans for thousands of years, primarily in the production of steel, which is an alloy made from iron and carbon. Iron is abundant in the Earth's crust and plays a crucial role in various biological processes, as it is a key component of hemoglobin in blood, which carries oxygen throughout the body. Its symbol Fe comes from the Latin word "ferrum," meaning iron.
