Copper, silver, and gold are all metallic elements that belong to the same group in the periodic table, known as Group 11 or the coinage metals. They are all excellent conductors of electricity and heat, have high luster and ductility, and are relatively unreactive chemically. Additionally, they are all commonly used in jewelry and as currency throughout history due to their relative scarcity and durability.
