Terbium
(gcide) | Terbium \Ter"bi*um\, n. [NL., fr. Ytterby, in Sweden. See
Erbium.] (Chem.)
A rare metallic element, found in certain minerals, as
gadolinite and samarskite, with other rare earths such as
ytterbium. Symbol Tb. Atomic number 65. Atomic weight
158.925.

Ytterbium
(gcide) | Ytterbium \Yt*ter"bi*um\, n. [NL., fr. Ytterby, in Sweden. See
Erbium.] (Chem.)
A rare element of the boron group, sometimes associated with
yttrium or other related elements, as in euxenite and
gadolinite. Symbol Yb; provisional atomic weight 173.2. Cf.
Yttrium.
[1913 Webster]
Note: Ytterbium is associated with other rare elements, and
probably has not been prepared in a pure state.
