Gold has a density of 19.3 g/cm 3, almost identical to that of tungsten at 19.25 g/cm 3; as such, tungsten has been used in counterfeiting of gold bars, such as by plating a tungsten bar with gold. [16] [17] [18] [19] By comparison, the density of lead is 11.34 g/cm 3 , and that of the densest element, osmium , is 22.588 ± … See more Gold is a chemical element with the symbol Au (from Latin: aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, … See more Although gold is the most noble of the noble metals, it still forms many diverse compounds. The oxidation state of gold in its compounds ranges from −1 to +5, but Au(I) and Au(III) … See more On Earth, gold is found in ores in rock formed from the Precambrian time onward. It most often occurs as a native metal, typically in a metal solid solution with silver (i.e. as a gold/silver alloy). Such alloys usually have a silver content of 8–10%. Electrum is … See more According to the United States Geological Survey in 2016, about 5,726,000,000 troy ounces (178,100 t) of gold has been accounted for, of … See more Gold is the most malleable of all metals. It can be drawn into a wire of single-atom width, and then stretched considerably before it breaks. Such nanowires distort via formation, … See more Gold production in the universe Gold is thought to have been produced in supernova nucleosynthesis, and from the collision of neutron stars See more The earliest recorded metal employed by humans appears to be gold, which can be found free or "native". Small amounts of natural gold have been found in Spanish caves used during the late Paleolithic period, c. 40,000 BC.
