Gold is a rare metal. Its chemical symbol Au, is named after
Aurora, the Roman goddess of the dawn. The purity of gold is described by its
fineness in parts per 1,000 or by the carat scale. Pure gold is 24 carat or
The price of gold and other precious metals is quoted in terms of
troy ounces. The term "troy" is derived from Troyes, France, a major trading
city of the Middle Ages. One troy ounce equals 31.1 grams. In 2009, gold
breached $1,000 an ounce, and continues to fluctuate.
Besides being a currency, gold has many uses, including:
Decoration - Gold
has been used for ornaments and decoration for more than 5,000 years. Its
resistance to corrosion helps it outlast paint.
Jewelry - Gold
was made in jewelry as early as 3,000BC.
Gold-reflective Glass -Gold
reflects heat and is so malleable that it is used to coat glass with a thin
film, which lets through light, but not heat. The use of reflective glass has
reduced cooling and heating costs by as much as 40 percent in some buildings.
Electronics - Gold
is a very good conductor of electricity, and it doesn't corrode or tarnish at
high or low temperatures. It is used in circuits in calculators, television
sets, computers, telephones and other electronics.
Satellites and Communications - Gold
is used in satellites as part of their electronic circuits and as a heat
Aerospace -Because the metal reflects heat, it is used to
protect astronauts, satellites and critical electronic components from damage
by hazardous x-rays and solar radiation found in space.
Medicine- Radioactive gold is used to treat
several types of cancer. Gold leaf is used to treat chronic ulcers and is used
in surgery to patch damaged blood vessels, nerves, bones and membranes.
Dentistry - Each year, U.S. dentists alone use about 30 tons of
gold for crowns, bridges, gold inlays and dentures because of their high
resistance to corrosion and tarnish.
(Cu) is a soft metal thatis a good conductor of heat and electricity. Its uses are
diverse, from serving as:
A building and waterproofing material
Piping for plumbing and water supplies
Cookware, refrigeration and air conditioning equipment
Copper wire, circuit boards and other electrical machines
