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 .CECeriaCeric dioxideCeric oxideCERIC OXIDE, CeO2.XH2OCeric oxide, ceriaCerium dioxideCerium oxideCerium oxide (Ce2O3)Cerium oxide (CeO2)Cerium sesquioxideCerium trioxideCerium, crudeCerium(4+) oxideCerium(III) oxideCerium(IV) oxideCerium(IV) oxide, dispersionCerium(IV)dioxideCerous oxideDicerium trioxideMolycomp 5310NeedlalNeedlal U15Needlal W10-01Needlal W15NidoralOpalineCe140.116139.905434035ceriumcerium7440-45-1[Ce]InChI=1S/CeGWXLDORMOJMVQZ-UHFFFAOYSA-N belongs to the class of inorganic compounds known as homogeneous lanthanide compounds.
