When was gold first discovered to be an element rather than a compound?
Quick Answer
Gold was recognized as a chemical element in the earliest days of modern chemistry, but its elemental nature was already understood in antiquity. The key scientific milestone was not discovery, but later classification in the periodic table.
The Full Story
Gold is one of the few substances known since antiquity, so there is no single discovery date like there is for many elements. Ancient civilizations already knew gold was a distinct metal and valued it for its rarity and resistance to corrosion. In modern chemistry, gold was later placed among the transition metals and understood in terms of atomic structure. Because it was known so early, gold is a good example of an element recognized long before the periodic table existed.
