The chemical element represented by the symbol 'Fe' is iron. This metallic element has an atomic number of 26 and is one of the most abundant elements in the Earth’s crust. Iron is vital for various industrial processes and is widely used in construction, manufacturing, and the production of steel, which is essential for infrastructure development. In addition, iron plays a crucial role in biological systems; it is a key component of hemoglobin, which transports oxygen in the blood of vertebrates. The element’s properties, such as strength and malleability, make it a cornerstone of modern technology and engineering.
