Silver is a chemical element with the symbol Ag and atomic number 47.  A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal.  The metal is found in the Earth's crust in the pure free elemental form as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite.  Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.

     Silver has long been valued as a precious metal.  Silver metal is used in many bullion coins, sometimes alongside gold.  White it is more abundant than gold, it is much less abundant as a native metal.  Its purity is typically measured on a per-mile basis;  a 94%-pure alloy is described as "0.940 fine".   As one of the seven metals of antiquity, silver has had an enduring role in most human cultures.

     Other than in  currency and as an investment medium silver is used in solar panels, water filtration, jewellery, ornaments, high-value tableware and utensils in electrical contacts and conductors, in specialized mirrors, window coatings, in catalysis of chemical reactions as a colorant in stained glass and in specialized confectionery.  Its compounds are used in photographic and X-ray film.
