Other metals appear golden, but only when they are oxidized.Most of the Earth’s gold came from meteor bombardments occurring around 200 million years after the planet formed.Gold is one of a handful of elements known since ancient times because it occurs in pure form naturally. Prehistoric humans also knew carbon, iron, copper, sulfur, zinc, silver, and mercury.The element symbol Au comes from the old Latin name for gold, aurum, which means “shining dawn” or “sunrise glow.” The modern word goldis a Germanic word meaning “yellowish green.”Atomic Number: 79Symbol: AuAtomic Weight: 196.9665Discovery: Gold has been known since prehistoric time.Chen, Jennifer; Lampel, Heather (2015). “Gold Contact Allergy: Clues and Controversies.” Dermatitis 26(2): 69-77. doi:10.1097/DER.0000000000000101Kelly, P.
