Gold

Gold is the most malleable and ductile metal in the world. It occupies place number 79 in the periodic table of elements.
Gold’s natural color is bright yellow, which makes it very unique, since most metals’ natural colors take a more grayish tone. That happens because of density of loosely bound (valence) electrons; those electrons oscillate as collective “plasma”. A good example is silver and its grayish color and cooper, which takes a more reddish tone; where gold, would be in the middle and up on the color spectrum graph.
A total of 171,300 tons of gold have been mined in human history, according to GFMS (formerly, Gold Fields Mineral Services) as of 2011. This is roughly equivalent to 5.5 billion Troy ounces or, in terms of volume, about 8876 m3. The world consumption of new gold produced is about 50% in jewelry, 40% in investments, and 10% in industry.
