Year of Discovery of the Elements

Unit

The year in which a chemical element was first discovered or isolated. Some elements such as gold, copper, and iron have been known since antiquity. Others were identified through systematic chemical analysis in the 18th and 19th centuries, while the most recent were synthesized in particle accelerators.

Data available for 118 of 118 elements. Highest: Tennessine (2010 year). Lowest: Copper (-8000 year).
