  • Chemical and Physical Properties of Gold

    Gold is one of the few elements that can be found in its native state. Gold is the most malleable and ductile metal. One ounce of gold can be beaten out to 300 ft 2 or stretched into a wire 2000 kilometers long (1 μm thick). The melting point of gold is an assigned value which serves as a calibration point for the International Temperature Scale and International Practical Temperature Scale.
