 * <span style="background-color: #c0c0c0; font-family: Georgia,serif;">Name: **<span style="font-family: Georgia,serif;"> **<span style="font-family: Georgia,serif;">Cerium was the first rare earth element to be discovered. It was isolated in 1839 by Swedish chemist Carl Gustav Mosander (1797-1858). Mosander was studying a new rock that had been discovered outside the town of Bastnas, Sweden. Mosander named the new element cerium, in honor of the asteroid Ceres that had been discovered in 1801. **<span style="font-family: Georgia,serif;">

Also it is used for making aluminum alloys, incandescent gas mantles, petroleum refining, and arc lighting. ** <span style="font-family: Georgia,serif;">
