Gold

Gold is a chemical component with the symbol Au that springs up from the Latin derivative aurum that means shining dawn and with the atomic number 79. It is an very sought-after valuable metal which, for many centuries, has been utilized as wealth; build up of value and in costume jewelry. The metal resembles as nuggets or grain like structures in rocks, subversive "veins" and in alluvial deposits. It is one of the currency metals.

Gold is solid, squashy, glossy and the most vulnerable and pliable of the known metals. 14k gold has a luminous yellow color by tradition considered gorgeous. Gold formed the foundation for the gold bars used before the fall down of the Bretton Woods system. It is explicitly against IMF norms to base any coinage aligned with gold bars for all IMF member states.

Chemically, gold charm is a tri-valent and uni-valent changeover metal. Gold does not act in response with the majority of chemicals, but is deteriorated by chlorine, fluorine, aqua regia and cyanide. Gold disbands in mercury, resulting amalgam alloys, but does not act in response with it. Gold is non-soluble in nitric acid, which will melt silver and other base metals, and this is the basis of the gold cleansing practice known as "inquartation and parting".

Gold is the most vulnerable and pliable metal; a single gram can be packed down into a pane of one square meter, or a bit into 300 square feet. Gold leaf can be flattened thin enough to be converted into semi-transparent. The transmitted luminosity appears greenish blue, for the reason that gold powerfully reflects yellow and red.
