What is a fun fact about cerium?
Cerium is the 25th-most-abundant element, making it as prevalent as copper. In air, cerium oxidizes quickly, forming a scale that sloughs off such that a centimeter-sized sample completely corrodes in 1 year. Cerium was discovered in 1803 by Swedish chemist Jöns Jakob Berzelius and physicist Wilhelm Hisinger.
What makes cerium special?
Cerium is a malleable, soft, ductile, iron-grey metal, slightly harder than lead. It is very reactive: it tarnishes readily in the air, it oxidizes slowly in cold water and rapidly in hot water. It dissolves in acids. It can burn when heated or scratched with a knife.
Is cerium rare or common?
rare earth element
Although cerium is a rare earth element, it is relatively abundant in the earth’s crust. Among the lanthanides, it is the most abundant. It is one of the 78 common elements in the earth’s crust, and ranks 25th in occurrence at an average distribution of 20–60 ppm.
Is cerium a solid liquid or gas?
Cerium is a chemical element with symbol Ce and atomic number 58. Classified as a lanthanide, Cerium is a solid at room temperature.
What is cerium used for in everyday life?
Uses of cerium Cerium oxide is used in incandescent gas mantles, as a glass polishing agent and as a catalyst in self-cleaning ovens. Cerium is also extensively used in the film and television industry in carbon arc lighting for studio lighting and projector lights.
How much is cerium worth?
The price of the rare earth oxide cerium oxide is expected to reach some 1,610 U.S. dollars per metric ton in 2030. In 2011, the price of cerium oxide reached a record high, at some 98,217 U.S. dollars per metric ton.
How much cerium is there in the world?
It is the most common of the lanthanides, followed by neodymium, lanthanum, and praseodymium. It is the 25th-most abundant element, making up 66 ppm of the Earth’s crust, half as much as chlorine and five times as much as lead….
