Yttrium (BioDeep_00000033097)

描述信息

Yttrium, also known as 39y or ytrio, is a member of the class of compounds known as homogeneous transition metal compounds. Homogeneous transition metal compounds are inorganic compounds containing only metal atoms,with the largest atom being a transition metal atom. Yttrium can be found in a number of food items such as cucumber, italian sweet red pepper, turnip, and red beetroot, which makes yttrium a potential biomarker for the consumption of these food products. Yttrium can be found primarily in cerebrospinal fluid (CSF) and saliva. Yttrium is a chemical element with symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a "rare-earth element". Yttrium is almost always found in combination with lanthanide elements in rare-earth minerals, and is never found in nature as a free element. 89Y is the only stable isotope, and the only isotope found in the Earths crust .
An element of the rare earth family of metals. It has the atomic symbol Y, atomic number 39, and atomic weight 88.91. In conjunction with other rare earths, yttrium is used as a phosphor in television receivers and is a component of the yttrium-aluminum garnet (YAG) lasers.
