Copper
Copper is a chemical element in the periodic table that has the symbol Cu and atomic number 29. Copper is a reddish-colored metal, with a high electrical and thermal conductivity. Copper has its characteristic color because it reflects red and orange light and absorbs other frequencies in the visible spectrum, due to its band structure. Contrast this with the optical properties of silver, gold and aluminium.
