Penemu Unsur Kimia

Who discovered the element gold, silver, copper, neon, etc…?

Below is a list of all of the known elements, who they were discovered by and the year they were discovered. Some elements, such as gold, silver and iron, have been known since ancient times, so it is impossible to credit a single person for their discovery. Other elements were discovered around the same time by two or more scientists who were working independently of each other. In these cases, each scientist is listed along with the year they made their discovery. Other elements were discovered by teams of scientists working together. In cases like this, the known members of the team are listed along with a single year of discovery. Click on an element’s name for the full story!
