Origin of 'cerium'
Main points about word origin
- The name 'cerium' comes from 'Ceres,' the Roman goddess of agriculture, reflecting its discovery shortly after the planet Ceres was found.
- Cerium was first isolated in 1803 by a Swedish chemist named Jรถns Jacob Berzelius and his student Wilhelm Hisinger, which emphasized the early collaborative efforts in science.
The name 'cerium' is derived from the asteroid Ceres, which was discovered in 1801, the same year cerium was identified by the Swedish chemist Jรถns Jacob Berzelius and the German chemist Wilhelm Hisinger. Cerium was isolated in 1803 by the Swedish chemist Carl Gustaf Mosander, who discovered a number of its compounds. It was the first of the rare earth elements to be identified and has since played a significant role in various industrial applications. Over the years, cerium's importance has grown, particularly in the field of materials science, where its unique properties are exploited in catalysis and electronic applications.
