Crystalline gold is not all created […] Some gold salts do have anti-inflammatory properties and at present two are still used as pharmaceuticals in the treatment of arthritis and other similar conditions in the US (sodium aurothiomalate and auranofin). The Aztecs regarded gold as the product of the gods, calling it literally "god excrement" (teocuitlatl in Nahuatl), and after Moctezuma II was killed, most of this gold was shipped to Spain. Less commonly, addition of manganese, indium, and other elements can produce more unusual colors of gold for various applications. Cyanide is a highly poisonous chemical, which can kill living creatures when exposed in minute quantities. Liquid nitrogen (made by distilling liquid air) boils at 77.4 kelvins (−195.8°C) and is used as a coolant. Mediterranean deep waters contain slightly higher concentrations of gold (100–150 femtomol/L) attributed to wind-blown dust and/or rivers. The chemical symbol for Radon is Rn. Sodium is a soft, silvery-white, highly reactive metal. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins. In the Book of Exodus, the Golden Calf is a symbol of idolatry, while in the Book of Genesis, Abraham was said to be rich in gold and silver, and Moses was instructed to cover the Mercy Seat of the Ark of the Covenant with pure gold. in. These drugs have been explored as a means to help to reduce the pain and swelling of rheumatoid arthritis, and also (historically) against tuberculosis and some parasites.. Winners of athletic events and other graded competitions are usually awarded a gold medal. The chemical symbol for Osmium is Os. γ: 90.000°. The chemical symbol for Tellurium is Te. Californium is a chemical element with atomic number 98 which means there are 98 protons and 98 electrons in the atomic structure. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. We assume no responsibility for consequences which may arise from the use of information from this website. Gold is also used in infrared shielding, colored-glass production, gold leafing, and tooth restoration. Uranium has the highest atomic weight of the primordially occurring elements. Caesium is a soft, silvery-gold alkali metal with a melting point of 28.5 °C, which makes it one of only five elemental metals that are liquid at or near room temperature. The chemical symbol for Praseodymium is Pr. Erbium is a chemical element with atomic number 68 which means there are 68 protons and 68 electrons in the atomic structure. Yttrium crystals do not occur in nature. Silicon is a hard and brittle crystalline solid with a blue-grey metallic lustre, it is a tetravalent metalloid and semiconductor. Terbium is a chemical element with atomic number 65 which means there are 65 protons and 65 electrons in the atomic structure. The discovery of the deposit in 1886 launched the Witwatersrand Gold Rush. Curium is a hard, dense, silvery metal with a relatively high melting point and boiling point for an actinide. Gold played a role in western culture, as a cause for desire and of corruption, as told in children's fables such as Rumpelstiltskin—where Rumpelstiltskin turns hay into gold for the peasant's daughter in return for her child when she becomes a princess—and the stealing of the hen that lays golden eggs in Jack and the Beanstalk.  The Proto-Indo-European ancestor of aurum was *h₂é-h₂us-o-, meaning "glow". The chemical symbol for Tin is Sn. One of their largest mines was at Las Medulas in León, where seven long aqueducts enabled them to sluice most of a large alluvial deposit. Cerium is the second element in the lanthanide series.  However, the price then began a slow decline towards $1200 per troy ounce in late 2014 and 2015. Similarly, gold is associated with perfect or divine principles, such as in the case of the golden ratio and the golden rule. The chemical symbol for Germanium is Ge. South Africa, which had dominated world gold production for most of the 20th century, had declined to sixth place. This word is derived from the same root (Proto-Indo-European *h₂u̯es- "to dawn") as *h₂éu̯sōs, the ancestor of the Latin word Aurora, "dawn". Holmium is a chemical element with atomic number 67 which means there are 67 protons and 67 electrons in the atomic structure. Terbium is a silvery-white, rare earth metal that is malleable, ductile, and soft enough to be cut with a knife. 600 BC Olympic Games and many other metals of the lanthanide series spheres fit the.
