Gold is a chemical element. It is a precious metal which has been used as money. Gold is found in nature as nuggets or grains in rocks, underground and in deposits. It is a soft, shiny, yellow metal, and is normally measured in Karats. A Karat refers to how much of a substance is gold, with 14 Karat being the most common. Gold is usually mixed with other elements because of how soft and pliable it is.
Gold is the basis for a monetary standard used by the International Monetary Fund (IMF) and the Bank for International Settlements (BIS).
Because gold is highly conductive and very resistant to oxidation, it is vital in electronics. Gold plating is used on switch contacts, printed circuit boards, and device leads. There is enough gold in electronic devices to make it worthwhile to process discarded devices in order to reclaim the gold in them.
Gold was one of the three Gifts of the Magi, along with frankincense and myrrh.[1]
Gold is also used in jewelry. However, the New Testament instructs Christian women not to wear gold or pearls.[2] Other uses of gold include aerospace, awards, bullion, coinage, computers, currency backing, dentistry, electronics, glassmaking, gold gilding and gold leaf and medical. [3]
