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"
