A Bit About Gold 

Gold is the most malleable and ductile metal. One ounce of gold can be beaten out to 300 ft2. 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. Gold is usually alloyed to increase its strength. Pure gold is measured in troy weight, but when gold is alloyed with other metals the term karat is used to express the amount of gold present.
