*’gold’ is 1 of a variety of yellow-orange color blends used to give the impression of the color of the element ‘gold’*

The web color gold is sometimes referred to as golden to distinguish it from the color metallic gold.
The use of gold as a color term in traditional usage is more often applied to the color “metallic gold” (shown below).
The first recorded use of golden as a color name in English was in 1300 to refer to the element gold and in 1423 to refer to blond hair.
Metallic gold, such as in paint, is often called goldtone or gold-tone.
In heraldry, the French word or is used.
In model building, the color gold is different from brass.
(a shiny or metallic silvertone object can be painted with transparent yellow to obtain goldtone, something often done with Christmas decorations)
(chemical element)
(atomic #79)
(the symbol Au)
(from latin “aurum”)
(from proto-indo-european word for “to shine / to gleam / to be yellow or green”)
(in its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable and ductile metal)
(chemically, ‘gold’ is a ‘transition metal’ and a ‘group 11’ element)
(it is one of the least reactive chemical elements, and is solid under standard conditions)
(the metal therefore occurs often in free elemental (native) form, as nuggets or grains, in rocks, in veins and in alluvial deposits)
(it occurs in a solid solution series with the native element ‘silver’ (as ‘electrum’) and also naturally alloyed with ‘copper’ and ‘palladium’)
(less commonly, it occurs in minerals as gold compounds, often with ‘tellurium’ (‘gold tellurides’))
(gold’s atomic number of 79 makes it one of the higher atomic number elements that occur naturally in the universe)
(it is thought to have been produced in ‘supernova nucleosynthesis’ and from the collision of ‘neutron stars’ and to have been present in the dust from which the ‘solar system’ formed)
(because the ‘earth’ was ‘molten’ when it was just formed, almost all of the gold present in the early earth probably sank into the ‘planetary core’)
(therefore, most of the gold that is present today in the earth’s crust and mantle is thought to have been delivered to earth later, by asteroid impacts during the ‘late heavy bombardment’, about 4 billion years ago)
(‘gold’ resists attack by individual acids, but ‘aqua regia’ (literally “royal water”, a mixture of ‘nitric acid’ and ‘hydrochloric acid’) can dissolve it)
(the acid mixture causes the formation of a ‘soluble tetrachloroaurate anion’)
(it is insoluble in ‘nitric acid’, which dissolves silver and base metals, a property that has long been used to refine gold and to confirm the presence of gold in metallic objects, giving rise to the term acid test)
(‘gold’ also dissolves in ‘alkaline’ solutions of ‘cyanide’, which are used in ‘mining’ and ‘electroplating’)
(‘gold’ dissolves in ‘mercury’, forming ‘amalgam alloys’, but this is not a chemical reaction)
(‘gold’ is a ‘precious metal’ used for coinage, jewelry, and other arts throughout recorded history.)
(in the past, a ‘gold standard’ was often implemented as a monetary policy within and between nations, but gold coins ceased to be minted as a circulating currency in the 1930s, and the ‘world gold standard’ was abandoned for a ‘fiat currency system’ after 1976)
(the historical value of ‘gold’ was rooted in its relative rarity, easy handling and minting, easy smelting and fabrication, resistance to corrosion and other chemical reactions (‘nobility’), and distinctive color)
(a total of 183,600 tonnes of gold is in existence above ground, as of 2014)
(this is equivalent to 9513 m3 of gold)
(the world consumption of new gold produced is about 50% in jewelry, 40% in investments, and 10% in industry)
(gold’s ‘high malleability’, ‘ductility’, ‘resistance to corrosion and most other chemical reactions’, and ‘conductivity of electricity’ have led to its continued use in corrosion-resistant electrical connectors in all types of computerized devices (its chief industrial use))
(‘gold’ is also used in ‘infra-red shielding’, ‘colored-glass production’, ‘gold leafing’, and ‘tooth restoration’)
.
(certain gold salts are still used as ‘anti-inflammatories’ in medicine)
