The symbol for the element Copper is "Cu." This symbol is derived from the Latin word "cuprum," which means "from Cyprus," as the island was once a major source of copper in ancient times. Copper is a transition metal with atomic number 29. It is known for its excellent electrical conductivity, malleability, and ductility, making it an essential material in electrical wiring, plumbing, and various industrial applications. Copper's reddish-brown color and resistance to corrosion also make it valuable in decorative arts and architecture, contributing to its widespread use throughout history.
