A soft, malleable, silvery-white metallic element discovered mostly in ores of zinc and tin, made use of as a plating over silver in making mirrors, in plating aircraft bearings, as well as in substances for making transistors. Atomic quantity 49; atomic fat 114.82; melting point 156.61°C; boiling-point 2,080°C; specific-gravity 7.31; valence 1, 2, 3. See dining table at element.
A metallic substance factor (symbolization In) with an atomic range 49.
an uncommon metallic element, of atomic number 49, found in certain ores of zinc, in the form of its characteristic spectrum of two indigo blue outlines; for this reason, its name. In features it resembles zinc, being white or lead gray, soft, malleable and easily fusible, in its chemical relation it resembles aluminum or gallium (valence +3). Symbolization In. Atomic body weight, 114.82.
Chemical sign, In; atomic weight, 113.7. A rare metallic factor found in the zinc-blende of Freiberg, Saxony, plus some various other localities, and found in the shape of the spectroscope: so called from its providing a blue range into the range.
an uncommon soft silvery metallic element; occurs in little volumes in sphalerite
