Description

Gold is Gold colored. It is the most malleable and ductile metal known. There is only one stable isotope of Gold, and five radioisotopes of Gold, ¹⁹⁵Au being the most stable with a half-life of 186 days. Gold is used as a monetary standard, in jewelry, dentistry, electronics. ¹⁹⁸Au is used in treating cancer and some other medical conditions. Gold has been known to exist as far back as 2600 BC. Gold comes from the Anglo-Saxon word Gold. Its symbol, Au, comes from the Latin word aurum, which means Gold. Gold is not particularly toxic, however it is known to cause damage to the liver and kidneys in some.

Uses

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.
