Gold. Gold is metallic, with a yellow colour when in a mass, but when finely divided it may be black, ruby, or purple. It is the most malleable and ductile metal 1 ounce (28 g) of gold can be beaten out to 300 square feet. It is a soft metal and is usually alloyed to give it strength.It is number 79 on the periodic table of elements. Gold is not magnetic, but it is an excellent conductor of electricity. Its melting point is 1945 F. Gold is not corroded or tarnished by moisture, or oxidized (rust) by the effects of oxygen and water, or affected by ordinary acids, as most other metals are.
