n. 金



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.
[1913 Webster]

2. Money; riches; wealth.
[1913 Webster]

For me, the gold of France did not seduce. --Shak.
[1913 Webster]

3. A yellow color, like that of the metal; as, a flower
tipped with gold.
[1913 Webster]

4. Figuratively, something precious or pure; as, hearts of
gold. --Shak.
