Cerium (BioDeep_00000033102)

描述信息

Cerium, also known as 58ce or cer, is a member of the class of compounds known as homogeneous lanthanide compounds. Homogeneous lanthanide compounds are inorganic compounds containing only metal atoms, with the largest atom being a lanthanide atom. Cerium can be found in a number of food items such as black-eyed pea, cucumber, spinach, and orange bell pepper, which makes cerium a potential biomarker for the consumption of these food products. Cerium can be found primarily in blood, cerebrospinal fluid (CSF), saliva, and urine. Cerium is a chemical element with symbol Ce and atomic number 58. Cerium is a soft, ductile and silvery-white metal that tarnishes when exposed to air, and it is soft enough to be cut with a knife. Cerium is the second element in the lanthanide series, and while it often shows the +3 oxidation state characteristic of the series, it also exceptionally has a stable +4 state that does not oxidize water. It is also traditionally considered one of the rare-earth elements. Cerium has no biological role and is not very toxic .
An element of the rare earth family of metals. It has the atomic symbol Ce, atomic number 58, and atomic weight 140.12. Cerium is a malleable metal used in many industrial applications including catalysts, additives to fuel to reduce emissions, and to glass and enamels to change their color.
