Who discovered the element cerium?

               There are three scientists who are credited with the discovery of the element cerium. While Swedish chemists Jons Jacob Berzelius and Wilhelm Hisinger discovered the element in Sweden, Martin Heinrich Klaproth, a German scientist, discovered it in his mother country. Both these discoveries were done independently of each other, in the year 1803.

               Cerium is named after the asteroid Ceres, a dwarf planet, which was discovered in 1801. The planet’s name derives from the Roman goddess of agriculture. Cerium is one abundant element.

               Cerium is a grey silvery-white metal. It decomposes slowly in cold water, and very rapidly in hot water. It is found in several minerals including allanite or orthrite, monazite, bastnasite, cerite and samarskite. Large deposits of cerium have been found in India, Brazil and in Southern California.

               Cerium burns when heated and is used in self-cleaning ovens. The film and television industry extensively uses it in carbon-arc lighting technology for studio lighting and projector lights.

               The atomic number of cerium is 58, and the atomic symbol is Ce.
