n. 金属名

金属名

gadolinium
n 1: a ductile silvery-white ductile ferromagnetic trivalent
metallic element of the rare earth group [synonym:
{gadolinium}, {Gd}, {atomic number 64}]

Gadolinium \Gad`o*lin"i*um\, n. [NL. See {Gadolinite}.] (Chem.)
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.
