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 Earth's crust .
