The element represented by the symbol "Fe" is iron. Iron is a transition metal known for its strength, durability, and abundance. With an atomic number of 26, iron is a critical component in numerous biological and industrial processes. It is essential for the formation of hemoglobin in blood, allowing for efficient oxygen transport in living organisms. Additionally, iron is a key material in construction, manufacturing, and engineering due to its high tensile strength and malleability. Iron can also react with oxygen to form rust, impacting infrastructure and equipment durability.
