  • Gold Discovered in California
  • January 24, 1848
  • Many people in California figured gold was there, but it was James W. Marshall on January 24, 1848, who saw something shiny in Sutter Creek near Coloma, California. He had discovered gold unexpectedly while overseeing construction of a sawmill on the American River.
  • Origin of the name: is the Anglo-Saxon word for the metal and the symbol comes from the Latin ‘aurum’, gold.
  • Also Gold is Metal and Transition Metal

Gold has been known since prehistoric times and was one of the first metals to be worked, mainly because it was to be found as nuggets or as particles in the beds of streams. Such was the demand that by 2000 BC the Egyptians began mining gold. The death mask of Tutankhamen, who died in 1323 BC, contained 100 kg of the metal. The royal graves of ancient Ur (modern Iraq), which flourished from 3800 to 2000 BC, also contained gold objects.

The minting of gold coins began around 640 BC in the Kingdom of Lydia (situated in what is now modern Turkey) using electrum, a native alloy of gold and silver. The first pure gold coins were minted in the reign of King Croesus, who ruled from 561–547 BC.

Gold definition: A soft, yellow, corrosion-resistant element, the most malleable and ductile metal, occurring in veins and alluvial deposits and recovered by mining or by panning or sluicing. Gold is a good conductor of heat and electricity, and is unaffected by air and most reagents. A good thermal and electrical conductor, gold is generally alloyed to increase its strength, and it is used as an international monetary standard, in jewelry, for decoration, and as a plated coating on a wide variety of electrical and mechanical components.The term carat describes the amount of gold present - 24 carats is pure gold.
