"Do not do unto others as you would that they should do unto you. Their tastes may not be the same." [George Bernard Shaw, 1898]
A soft yellow element that resists corrosion and is the most malleable and ductile metal. A good thermal and electrical conductor, gold is generally alloyed to increase its strength. Atomic number 79; atomic weight 196.967; melting point 1,064.2°C; boiling point 2,856°C; specific gravity 19.3; valence 1, 3.
|gold (gōld) Pronunciation Key
A soft, shiny, yellow element that is the most malleable of all the metals. It occurs in veins and in alluvial deposits. Because it is very durable, resistant to corrosion, and a good conductor of heat and electricity, gold is used as a plated coating on electrical and mechanical components. It is also an international monetary standard and is used in jewelry and for decoration. Atomic number 79; atomic weight 196.967; melting point 1,063.0°C; boiling point 2,966.0°C; specific gravity 19.32; valence 1, 3. See Periodic Table. See Note at element.
(1.) Heb. zahab, so called from its yellow colour (Ex. 25:11; 1 Chr. 28:18; 2 Chr. 3:5). (2.) Heb. segor, from its compactness, or as being enclosed or treasured up; thus precious or "fine gold" (1 Kings 6:20; 7:49). (3.) Heb. paz, native or pure gold (Job 28:17; Ps. 19:10; 21:3, etc.). (4.) Heb. betzer, "ore of gold or silver" as dug out of the mine (Job 36:19, where it means simply riches). (5.) Heb. kethem, i.e., something concealed or separated (Job 28:16,19; Ps. 45:9; Prov. 25:12). Rendered "golden wedge" in Isa. 13:12. (6.) Heb. haruts, i.e., dug out; poetic for gold (Prov. 8:10; 16:16; Zech. 9:3). Gold was known from the earliest times (Gen. 2:11). It was principally used for ornaments (Gen. 24:22). It was very abundant (1 Chr. 22:14; Nah. 2:9; Dan. 3:1). Many tons of it were used in connection with the temple (2 Chr. 1:15). It was found in Arabia, Sheba, and Ophir (1 Kings 9:28; 10:1; Job 28:16), but not in Palestine. In Dan. 2:38, the Babylonian Empire is spoken of as a "head of gold" because of its great riches; and Babylon was called by Isaiah (14:4) the "golden city" (R.V. marg., "exactress," adopting the reading _marhebah_, instead of the usual word _madhebah_).
