60 Gold Facts

Gold is money, money and property of the Age of Man began to discover gold.

Gold is a chemical element with the symbol Au (Aurum)

The atomic number for gold is 79

Gold has been used as coins, jewelry,
decoration since ancient times when human civilizations began clever record

Gold is derived from the earth's crust in the form of granules, the veins of rocks and alluvial

Physical gold is shiny, soft and heavy.

Gold is the softest metal on Earth

Gold is the most malleable metal in the world

Golden yellow shiny and not oxidized even in the water (not rusty)

Gold is used as a metal for the currency and it is a symbol of luxury and wealth of individual savings.

Gold is associated with all ideologies, religions and symbols, whether Islamic, Hindu, or atheist.

It is said by 161,000 tons (161juta kilograms) of gold have been extracted from the earth.

Gold played some role in the manufacture of computer, communications equipment, spacecraft, jet aircraft engines, airplanes, and other products.

Resistance to oxidation allows gold used widely in the manufacture of thin layers electroplated on the surface of electrical connectors to ensure a good connection.

Like silver, gold can form a hard amalgam with mercury, and is sometimes used for dental fillings.

Gold is the most passive, stable and very low react with other elements

Gold is the only element that is insoluble in nitric acid. Other metals such as Silver (Si) and other metals react with Nitric Acid.

Nitric acid is the main solution is used to determine the purity of gold.

In 2008, China has overtaken South Africa as the world's largest producer of gold. This is the first time that happened since South Africa began producing gold in 1905.

In the history of mankind, 161,000 tons of gold have been extracted can charge can only fill 2 Olympic size pool.

One gram of gold can be beaten into a one-size-meter long and one meter wide, or 1 ounce to 300 ft² (square 3300meter) ~ (57m x 57m)

Pure gold is malleable as smooth as possible so that it becomes almost transparent

Gold can be used as an alloy with other metals

Alloy resulting from the gold can change the hardness, strength, nature kelogamman (metallugical), the melting temperature and the change in the north of a gold quality.

Gold is used in modern industry as a conductor of heat and electricity.

Since gold is reflecting infrared radiation and visible light is good, the metal is used as a protective coating on a man-made satellite.

Gold does not react with air, moisture and strong corrosion agent.

Ion gold constantly undergoing a process of degradation and the resulting sediment is solid gold metal.

Pure gold 24karat has no taste and smell.

Gold is dense, one cubic meter of gold weighs 19,300kg.

The color of pure gold is metallic yellow

Only the gold, and copper Cesium is a metal that is not white or gray.

Gold has different reactions depending on the prevailing relativistic effects in atomic orbitals of the atoms on (79 - 2.8.18.18.32.1) (think of shooting stars that orbit the earth every time)

The gold alloy red rose can be generated with a mix of several compositions of copper (copper) and Silver (Silver)

Gold has only one form only in the form of natural isotopes and 18 other radioisotopes. Radioisotopes Au-195 is the most stable with a half-life of 186 days.

Gold widely used throughout the world as a currency peg. The amount of gold stored state bank with the same amount of banknotes printed for use in everyday affairs.

The amount of gold in the world is limited and on this day, gold production is decreasing.

In the 20th century, the world's gold reserves and market its business are getting smaller and valuation levels are fixed.

When the start of the First World War, the countries involved in the war re-use the gold to finance the campaigns of each battle.

after the Second World War, replaced gold with paper currency exchange in accordance with the method of Bretton Woods.

The value of the gold standard and exchange rate directly to the value of the currency has been stopped and now it is replaced with a fixed exchange rate.

Switzerland was the last country to peg their currencies (by 40%) in the value of gold after the International Monetary Fund (IMF) in 1999

Although gold is a noble metal, but it can produce a variety of sebatian.Aurik chloride (AuCl3) and Chlorauric acid (HAuCl4) is the most common gold compounds. The human body can not devour gold compounds are usually not very toxic. However, over 50% reported arthritis patients treated with the drug containing gold liver damage and kidney.

Pure gold is very soft for everyday use and usually it is alloyed with other metals to make it harder.

The gold content in the alloy is measured using the unit Karat (k)

​​Pure gold is measured as 24karat (k)

Gold coins issued since 1526 until 1930 is in the form of gold 22karat (916).

Gold for investment does not require mechanical properties such as hard, so it's hard to wear normal 24karat formed to gold.

Gold coins issued by certain countries such as the American Gold Eagle, Britisj Gold Sovereign and South Africa is in the form 22karat Krugerran.

Gold is the purest in the world issued by Canada in the form of Canadian Gold Maple Leaf with a purity of 99.999% gold.

The melting point of gold is 1337.33 K (1064.18 ° C, 1947.52 ° F) and the boiling point 3129 K (2856 ° C, 5173 ° F)

The gold isotope Au-198, (half-life: 2.7 days) is used in the treatment of cancer and other diseases treatment.

Colloidal gold (gold nanoparticles) is an intensely colored solution that is currently studied in laboratories for medical and biology (biology). It is also the form used as gold paint on ceramics prior to ceramic burned.

Gold is used as a coating material to allow the biological material was observed under a scanning electron microscope.

The colors on gold is due to the frequency of the plasmons of gold lies in the range of vision, resulting in red and yellow colors reflected while blue color is absorbed. Only colloidal silver have the same interaction with light, but in a shorter frequency, thereby causing the color to yellow colloidal silver.

Gold is a poor conductor of heat and electricity well, and is unaffected by air and most reagents. Chemically, gold can not be altered by heat, moisture, and most corrosive agents, and therefore it is particularly suitable for use in coins and jewelry.

Gold is separated from ore using cyanide, amalgam, and smelting. Purification metal is usually conducted using electrolysis.

Gold is found in sea water at a concentration of 0.1 to 2 mg / ton depending on the position of the sample. However, to date, namely the year 2006 there was not any way that would result if gold profits derived from sea water.

Civilization Malay Srivijaya and Majapahit use gold as a currency for maritime trade.

Prophet Solomon and his great imperial palace and government decorate with gold.
