Index - 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, and ductile metal in a pure form. 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. Gold often
occurs in free elemental (native state), as nuggets
or grains, in rocks, veins, and alluvial deposits.
It occurs in a solid solution series with the native
element silver (as electrum), naturally alloyed with
other metals like copper and palladium, and mineral
inclusions such as within pyrite. Less commonly, it
occurs in minerals as gold compounds, often with tellurium
is resistant to most acids, though it does dissolve
in aqua regia (a mixture of nitric acid and hydrochloric
acid), forming a soluble tetrachloroaurate anion.
Gold is insoluble in nitric acid alone, which dissolves
silver and base metals, a property long used to refine
gold and confirm the presence of gold in metallic
substances, giving rise to the term 'acid test'. Gold
dissolves in alkaline solutions of cyanide, which
are used in mining and electroplating. Gold also dissolves
in mercury, forming amalgam alloys, and as the gold
acts simply as a solute, this is not a chemical reaction.
relatively rare element, gold is a precious
metal that has been used for coinage, jewelry, and
other arts throughout recorded history. In the past,
a gold standard was often implemented as a monetary
policy. 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 the
Nixon shock measures of 1971.
2020, the world's largest gold producer was China,
followed by Russia and Australia. A total of around
201,296 tonnes of gold exists above ground, as of
2020. This is equal to a cube with each side measuring
roughly 21.7 meters (71 ft). 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 infrared shielding, production of colored glass,
gold leafing, and tooth restoration. Certain gold
salts are still used as anti-inflammatories in medicine.

Expo (AGE), held last week at Sydney Exhibition Centre @ Glebe Island

there was much to see and do at the events new venue. Live animal encounters,
a life size replica of the Delorean from the Back to the Future movie franchise,
free pizza and coffee samples and the chance to win free trips to Las Vegas helped
to draw a crowd described as by the event organiser as remarkable.

for exhibitors and an endorsement of the approach taken by AEG Ogden to the task
of operating the venue and the New South Wales Governments provision of
additional visitor transport options, commented Gaming Technologies Association

to Glebe Island during the Darling Harbour redevelopments.
Exhibition Centre @ Glebe Island has been purpose built to provide a fully functioning
event space while ICC Sydney, the new exhibition, conference and entertainment
complex in Darling Harbour is being developed.
