Fe, Cu, Pb

Iron (Fe), copper (Cu), and lead (Pb) are essential metals with distinct properties and uses. Iron is a strong, abundant metal primarily used in construction and manufacturing, forming the backbone of structures like buildings and bridges. Copper is known for its excellent electrical conductivity, making it valuable in electrical wiring and electronics. Lead, once widely used in paints and pipes due to its malleability, is now recognized for its health risks and is less commonly used. Each metal plays a significant role in industry and technology, with iron and copper being crucial for infrastructure and electronics, while lead's use is declining.
