The Chemistry and Uses of Gold, Silver, and Copper (Cu)
The precious metals, gold (Au), silver (Ag), and copper (Cu), possess unique physical features that lend way to a broad array of applications. Gold is extremely inert, resisting several corrosive reactions, rendering it appropriate for jewelry and devices. Silver, while somewhat inert than gold, is however a relatively effective conductor of power and temperature, leading to its application in film and electrical contacts. Copper, being an transition substance, is significantly greater active and is employed in wiring, plumbing, and multiple combinations, including brass and copper alloys. The potential to build stable compounds furthermore plays to their importance in contemporary technology.
