Properties of gold silver and platinum

Platinum is more ductile than gold, silver or copper, thus being the most ductile of pure metals, but it is less malleable than gold. [10] [11] The metal has excellent resistance to corrosion , is stable at high temperatures and has stable electrical properties. In mass, gold is a yellow-colored metal, although it may be black, ruby, or purple when finely divided. Gold is a good conductor of electricity and heat. It is not affected by exposure to air or to most reagents. It is inert and a good reflector of infrared radiation. The best prices for gold and silver are those that are most reliable.
