Iron is a chemical element with the symbol Fe and atomic number 26. It is one of the most abundant elements on Earth and is primarily used in the production of steel, which is essential for construction and manufacturing. Iron is known for its strength and durability, making it a vital material in various industries. In its pure form, iron is relatively soft and malleable, but it can be alloyed with other elements to enhance its properties. The process of rusting, which occurs when iron reacts with oxygen and moisture, is a common concern, leading to the development of protective coatings and treatments to prolong its lifespan.
