Title: Cerium
Post by: Rennhack on Nov 28, 2005, 09:16
An iron-gray, lustrous metal. It is malleable, and oxidizes very readily at room temperature, especially in moist air. The pure metal may ignite when scratched with a knife. Cerium-141, -143, and -144 are radioisotopes of cerium. They emit beta particles during radioactive decay.
