Definitions

from The American Heritage® Dictionary of the English Language, 5th Edition.

  • noun A soft, malleable, silvery-white metallic element found primarily in ores of zinc and tin, used in making fusible alloys, in plating aircraft bearings and mirrors, and in compounds for making liquid crystal displays and transistors. Atomic number 49; atomic weight 114.82; melting point 156.60°C; boiling point 2,072°C; specific gravity 7.31; valence 1, 2, 3. cross-reference: Periodic Table.

from The Century Dictionary.

  • noun Chemical symbol, In; atomic weight, 113.7. A rare metallic element found in the zinc-blende of Freiberg, Saxony, and some other localities, and discovered by means of the spectroscope: so called from its giving a blue line in the spectrum.

from the GNU version of the Collaborative International Dictionary of English.

  • noun (Chem.) A rare metallic element, of atomic number 49, discovered in certain ores of zinc, by means of its characteristic spectrum of two indigo blue lines; hence, its name. In appearance it resembles zinc, being white or lead gray, soft, malleable and easily fusible, but in its chemical relation it resembles aluminium or gallium (valence +3). Symbol In. Atomic weight, 114.82.
