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
(gold tellurides).
Gold
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.
A
relatively rare element,[6][7] 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.
In
2020, the world's largest gold producer was China,
followed by Russia and Australia.[8] A total of around
201,296 tonnes of gold exists above ground, as of
2020.[9] 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.[10] 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.

plated attractions at this years Australasian Gaming Expo (SYDNEY,
AUSTRALIA) 19 August 2014 – It was wins all round for visitors, exhibitors
and those behind the scenes at the 25th anniversary of the Australasian Gaming
Expo (AGE), held last week at Sydney Exhibition Centre @ Glebe Island 
In
addition to the regular displays of the latest gaming and hospitality equipment,
there was much to see and do at the event’s 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”. 
“This
year’s visitor attendance has been remarkable – which was both reassuring
for exhibitors and an endorsement of the approach taken by AEG Ogden to the task
of operating the venue and the New South Wales Government’s provision of
additional visitor transport options”, commented Gaming Technologies Association
(GTA) CEO Ross Ferrar. 
As
one of the first organisers to book space at Glebe Island, Ross and his team had
confidence in the interim venue from the get-go and he credits AGE 2014’s
success in no small part to the SEC@GI team. 
According
to SEC@GI Venue Operations Manager Marc Singerling, getting the little things
right is just as important as the big stuff. 
“Like
us, Ross and the team at GTA understand the importance of delivering the full
360 degree experience from the moment visitors and exhibitors step through the
door. Whether it’s the temperature of the coffee or getting just the right
lighting on each exhibitor stand, each touchpoint needs to complement the others. "It’s
a pleasure to work with them on this show and we’re thrilled to welcome them
to Glebe Island during the Darling Harbour redevelopments.” Sydney
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. (Casino
