  • n. A rare earth metallic element of the Lanthanide series, with a characteristic spectrum, found associated with yttrium and other rare earth elements. Symbol, Gd; it has an atomic number of 64, an atomic weight of 157.25 (C=12.011), and a valence of +3.

from The Century Dictionary and Cyclopedia

  • n. A supposed new element found with yttrium in gadolinite.
  • n. It belongs to the same family as yttrium. Its oxid is white, and its salts are colorless: atomic weight about 156. It perhaps represents a mixture of more than a single element.
