The 79th element on the Periodic Table, gold is a shiny yellowish transition metal that is soft, heavy (at 197 grams per mole), highly non-reactive and non-corrodible, highly ductile, and even more malleable and may be pounded into extremely thin foil. It is scarce and precious, and has been used as specie since ancient times though most industrial nations have ditched the gold standard and let the economy price their currency. Gold specie is back with style with e-gold. Gold also is an excellent conductor and is widely used in electronics, especially as an excellent plating for connectors, since it conducts well and does not corrode. (Silver conducts better and is cheaper, but is not as malleable and is easily tarnished.) Gold has also been used in dental fillings, in jewelry and other adornments and decorating due to its beautiful, lavish lustre.
