Legend

Name origin:	Anglo-Saxon: geolo (yellow); symbol from Latin: aurum (shining dawn).
Description:	Soft, malleable, bright yellow metal.
Discovered by:	Known to the ancients
Year:	--
Place:	Unknown
Sources:	Found in veins in the crust, with cooper ore and native compounds.
Use(s):	Very malleable. Used in electronics, jewelry and coins. It is a good reflector of infrared radiation, so a thin film of gold is applied to the glass of skyscrapers to reduce internal heating from sunlight.
