Gold \Gold\ (g[=o]ld), n. [AS. gold; akin to D. goud, OS. & G.
   gold, Icel. gull, Sw. & Dan. guld, Goth. gul[thorn], Russ. &
   OSlav. zlato; prob. akin to E. yellow. [root]49, 234. See
   Yellow, and cf. Gild, v. t.]
   [1913 Webster]
   1. (Chem.) A metallic element of atomic number 79,
      constituting the most precious metal used as a common
      commercial medium of exchange. It has a characteristic
      yellow color, is one of the heaviest substances known
      (specific gravity 19.32), is soft, and very malleable and
      ductile. It is quite unalterable by heat (melting point
      1064.4[deg] C), moisture, and most corrosive agents, and
      therefore well suited for its use in coin and jewelry.
      Symbol Au (Aurum). Atomic weight 196.97.
      [1913 Webster]

   Note: Native gold contains usually eight to ten per cent of
         silver, but often much more. As the amount of silver
         increases, the color becomes whiter and the specific
         gravity lower. Gold is very widely disseminated, as in
         the sands of many rivers, but in very small quantity.
         It usually occurs in quartz veins (gold quartz), in
         slate and metamorphic rocks, or in sand and alluvial
         soil, resulting from the disintegration of such rocks.
         It also occurs associated with other metallic
         substances, as in auriferous pyrites, and is combined
         with tellurium in the minerals petzite, calaverite,
         sylvanite, etc. Pure gold is too soft for ordinary use,
         and is hardened by alloying with silver and copper, the
         latter giving a characteristic reddish tinge. [See
         Carat.] Gold also finds use in gold foil, in the
         pigment purple of Cassius, and in the chloride, which
         is used as a toning agent in photography.
