Cerium Metal Description
Named for the Roman goddess of agriculture, Ceres, cerium is a silvery-white metal that easily oxidizes in the air. It is the most abundant of the rare earth elements and has many uses. For instance, cerium oxide is used as a catalyst in catalytic converters in automotive exhaust systems to reduce emissions, and is highly desirable for precision glass polishing. Cerium can also be used in iron, magnesium and aluminum alloys, magnets, certain types of electrodes, and carbon-arc lighting.
Cerium is the second element of the lanthanide series. In the periodic table, it appears between the lanthanides lanthanum to its left and praseodymium to its right, and above the actinide thorium. It is a ductile metal with a hardness similar to that of silver.
Its 58 electrons are arranged in the configuration, of which the four outer electrons are valence electrons and 6s energy levels are very close to each other, and the transference of one electron to the 5d shell is due to strong interelectronic repulsion in the compact 4f shell.
This effect is overwhelmed when the atom is positively ionised; thus Ce2+ on its own has instead the regular configuration ,
Although in some solid solutions it may be Most lanthanides can use only three electrons as valence electrons, as afterwards the remaining electrons are too strongly bound: cerium is an exception because of the stability of the empty f-shell and the fact that it comes very early in the lanthanide series, where the nuclear charge is still low enough until neodymium to allow the removal of the fourth valence electron by chemical means
