Some gold compounds exhibit aurophilic bonding, which describes the tendency of gold ions to interact at distances that are too long to be a conventional Au–Au bond but shorter than van der Waals bonding. The interaction is estimated to be comparable in strength to that of a hydrogen bond.

Wedding rings are typically made of gold. It is long lasting and unaffected by the passage of time and may aid in the ring symbolism of eternal vows before God and the perfection the marriage signifies. In Orthodox Christian wedding ceremonies, the wedded couple is adorned with a golden crown (though some opt for wreaths, instead) during the ceremony, an amalgamation of symbolic rites. [ further explanation needed] Although gold is the most noble of the noble metals, [33] [34] 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) dominate its chemistry. Au(I), referred to as the aurous ion, is the most common oxidation state with soft ligands such as thioethers, thiolates, and organophosphines. Au(I) compounds are typically linear. A good example is Au(CN) − 2, which is the soluble form of gold encountered in mining. The binary gold halides, such as AuCl, form zigzag polymeric chains, again featuring linear coordination at Au. Most drugs based on gold are Au(I) derivatives. [35] Johnson, P. B.; Christy, R. W. (1972). "Optical Constants of the Noble Metals". Physical Review B. 6 (12): 4370–4379.

Gold ' is cognate with similar words in many Germanic languages, deriving via Proto-Germanic * gulþą from Proto-Indo-European * ǵʰelh₃- ("to shine, to gleam; to be yellow or green"). [108] [109] Au(III) (referred to as auric) is a common oxidation state, and is illustrated by gold(III) chloride, Au 2Cl 6. The gold atom centers in Au(III) complexes, like other d 8 compounds, are typically square planar, with chemical bonds that have both covalent and ionic character. Gold(I,III) chloride is also known, an example of a mixed-valence complex. Scientific Opinion on the re-evaluation of gold (E 175) as a food additive".

Gold is thought to have been produced in supernova nucleosynthesis, and from the collision of neutron stars, [52] and to have been present in the dust from which the Solar System formed. [53]

A spokesperson for Regis Resources says it will be seeking to “recruit locally to fill as many positions as possible”, as well as hiring local suppliers. “That includes considering rosters for certain roles that make it possible for people like farmers to draw an off-farm income if they choose to.”

The European exploration of the Americas was fueled in no small part by reports of the gold ornaments displayed in great profusion by Native American peoples, especially in Mesoamerica, Peru, Ecuador and Colombia. 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. [94] However, for the indigenous peoples of North America gold was considered useless and they saw much greater value in other minerals which were directly related to their utility, such as obsidian, flint, and slate. [95] El Dorado is applied to a legendary story in which precious stones were found in fabulous abundance along with gold coins. The concept of El Dorado underwent several transformations, and eventually accounts of the previous myth were also combined with those of a legendary lost city. El Dorado, was the term used by the Spanish Empire to describe a mythical tribal chief (zipa) of the Muisca native people in Colombia, who, as an initiation rite, covered himself with gold dust and submerged in Lake Guatavita. The legends surrounding El Dorado changed over time, as it went from being a man, to a city, to a kingdom, and then finally to an empire.
