#Yttriumelement 
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. 89 Y is the only stable isotope, and the only isotope found in the Earth's crust.  #transitionmetal
Yttrium is a soft, silver-metallic, lustrous and highly crystalline transition metal in group 3. As expected by periodic trends, it is less electronegative than its predecessor in the group, scandium, and less electronegative than the next member of period 5, zirconium; additionally, it is more electronegative to its successor in its group, lanthanum, being closer in electronegativity to the later lanthanides due to the lanthanide contraction.Yttrium is the first d-blockelement in the fifth period...
