Gold's great virtues of malleability, ductility, reflectivity, resistance to corrosion and unparalleled ability as a thermal and electrical conductor mean it is used in a wide variety of industrial applications consuming close to 300 tonnes annually. Gold (Au, from Latin "Aurum" (World Book Dictionary) is the most non-reactive of all metals -- it is benign in all natural and industrial environments. Gold never reacts with oxygen (one of the most active elements), which means it will not rust or tarnish. Gold is among the most electrically conductive of all metals. Since electricity is basically the flow of charged particles in a cur
