| ytterbic | <chemistry> Pertaining to, or derived from, ytterbium; containing ytterbium. Source: Websters Dictionary (01 Mar 1998) |
| ytterbium | <chemistry, element> A rare element of the boron group, sometimes associated with yttrium or other related elements, as in euxenite and gadolinite. Cf. Yttrium. Ytterbium is associated with other rare elements, and probably has not been prepared in a pure state. Atomic weight: 173.2 Abbreviation: Yb Origin: NL, fr. Ytterby, in Sweden. See Erbium. (30 Mar 1998) |
| yttria | <chemistry> The oxide, Y2O3, or earth, of yttrium. Origin: NL. See Yttrium. Source: Websters Dictionary (01 Mar 1998) |
| yttric | <chemistry> Pertaining to, derived from, or containing, yttrium. Source: Websters Dictionary (01 Mar 1998) |
| yttrious | <chemistry> Same as Yttric. Source: Websters Dictionary (01 Mar 1998) |
| yttrium | <chemistry> A rare metallic element of the boron-aluminium group, found in gadolinite and other rare minerals, and extracted as a dark gray powder. Symbol Y. Atomic weight. Alternative forms: ittrium. Associated with yttrium are certain rare elements, as erbium, ytterbium, samarium, etc, which are separated in a pure state with great difficulty. They are studied by means of their spark or phosphorescent spectra. Yttrium is now regarded as probably not a simple element, but as a mixture of several substances. Origin: NL, from Ytterby, in Sweden. See Erbium. Source: Websters Dictionary (01 Mar 1998) |
| yttrium isotopes | Stable yttrium atoms that have the same atomic number as the element yttrium, but differ in atomic weight. Y-89 is the only naturally occurring stable isotope of yttrium. (12 Dec 1998) |
| yttrium radioisotopes | Unstable isotopes of yttrium that decay or disintegrate emitting radiation. Y atoms with atomic weights 82-88 and 90-96 are radioactive yttrium isotopes. (12 Dec 1998) |
| yttrium-90 | An artificial radioactive isotope with a physical half-life of 2.67 days which decays with the emission of a 2.282 Mev b particle; used as an implant in pituitary ablation. (05 Mar 2000) |
| yttro-cerite | <chemical> A mineral of a violet-blue colour, inclining to gray and white. It is a hydrous fluoride of cerium, yttrium, and calcium. Source: Websters Dictionary (01 Mar 1998) |
