erbium
n 1: a trivalent metallic element of the rare earth group;
occurs with yttrium [synonym: {erbium}, {Er}, {atomic number
68}]

Erbium \Er"bi*um\, n. [NL. from Ytterby, in Sweden, where
gadolinite is found. Cf. {Terbium}, {Yttrium}, {Ytterbium}.]
(Chem.)
A rare earth element of the lanthanide series associated with
several other rare elements in the mineral gadolinite from
Ytterby in Sweden. Symbol Er. It has atomic number 68 and an
atomic weight of 167.26. The pure element is metallic with a
bright, silvery luster. It is relatively stable in air, not
oxidizing as quickly as some other rare earths. Its salts are
rose-colored and give characteristic spectra, and the pink
oxide has been added as a colorant in glass and porcelain
enamel glazes. Its sesquioxide {Er2O3} is called erbia.
--HCP61
[1913 Webster PJC]
