Gold


1.    Gold is used to treat many ear and eye diseases, it is used in jewelry, and gold foil is used as a topping for fancy deserts. Also, gold was the first metal widely known to our species. Gold is the easiest of all metals to work. Many early civilizations equated gold with gods and rulers. Homer, in the "Iliad" and "Odyssey," makes mention of gold as the glory of the immortals and a sign of wealth among ordinary humans. In Genesis 2:10-12, we learn of the river Pison out of Eden, and "the land of Havilah, where there is gold: and the gold of that land is good?". In the modern world, gold has become very rare; therefore, the price has risen.

Gold is both malleable and ductile and is a heavy metal, as well as it conducts electricity. Gold leaf is translucent and the transmitted light is greenish blue (gold metal reflects yellow and red, leaving the greenish blue color). One gram of gold can be drawn into a thin wire; therefore, it is ductile. The melting point is 1337.33 K, the boiling point is 3129 K, and the liquid range is 1791.67  K. Gold is not reactive.
