Gold has been known to humans for nearly 5,000 years. Objects made of the metal dating to 2600 B.C. have been found in royal tombs of ancient civilizations. It has been used routinely by nearly all cultures for coins, jewelry, and artwork. The element's chemical symbol, Au, is derived from the ancient Latin word for the element, aurum.
o Why is the element important?
In a 1986 study, experts estimated that 121,000 metric tons of gold have been mined throughout history. Of that amount, about 18,000 metric tons were used for industrial, research, health, and other uses in which the metal was discarded after it was used. Of the remaining 103,000 metric tons of gold, about a third has been made into gold bars and held by national banks as security for national money systems. The remaining 68,000 tons of gold are owned by private individuals in the form of jewelry, coin, artwork, or bullion.
gold also is used in some currency because it does not oxidize.
o What are some common uses of/for the element?
A good conductor of electricity and heat, gold is often used to manufacture electrical connectors and printed circuit boards. In space systems, gold is used to reflect infrared radiation, to help shield spacecraft from the heat of the sun, and to coat mirrors on telescopes that are sensitive to infrared light. On Earth, buildings are sometimes protected from the sun's heat with the use of thin coatings made from gold.
o Are there important isotopes of the element?
