  • periodic table
  • Chemically, yttrium resembles those elements more closely than its neighbor in the periodic table, scandium , and if physical properties were plotted against atomic number , it would have an apparent number of 64.5 to 67.5, placing it between the lanthanides gadolinium and erbium . (wikipedia.org)
  • rare-earth mi
  • Yttrium is almost always found in combination with lanthanide elements in rare-earth minerals , and is never found in nature as a free element. (wikipedia.org)
  • The similarities of yttrium to the lanthanides are so strong that the element has historically been grouped with them as a rare-earth element , and is always found in nature together with them in rare-earth minerals . (wikipedia.org)
