Gold has been known since prehistoric times and was the first metal used by humans.

Gold artifacts dated to 5000 years ago have been found in Egyptian tombs.

Gold of 98% purity has been found in Nahal Qunah in the ancient kingdom of Israel, dating from about 6000 years ago. From the Latin word aurum meaning gold 95 1944 Glenn Seaborg, Ralph James., L. Morgan, Albert Ghiorso USA From the English word "America"

Gold is used in coinage and is a standard for monetary systems in many countries.

It is also extensively used for jewelry, decoration, dental work, and for plating.

Gold is used widely in microelectronic circuits to ensure reliable, corrosion-resistant and static-free performance.

Gold leaf, flake or dust is used in some gourmet foods as decorative ingredient.
