The Chemistry and Uses of Gold, Silver, and Copper (Cu)
The valuable metals, gold (Au), silver (Ag), and copper (Cu), possess remarkable chemical characteristics that provide themselves to a broad range of uses. Gold is extremely unreactive, avoiding several corrosive interactions, rendering it appropriate for jewelry and devices. Silver, while somewhat passive than gold, is however a relatively good conductor of power and warmth, resulting to its use in imaging and power contacts. Copper, existing an base metal, is much greater active and tends to be used in cabling, water systems, and multiple mixtures, including brass and brass. The capacity to form durable compounds also plays to their significance in contemporary technology.
