Silver is a chemical element with symbol Ag (Greek: άργυρος
árguros, Latin: argentum, both from the Indo-European root *h₂erǵ- for
“grey” or “shining”) and atomic number 47. 
A soft, white,
lustrous transition metal, it possesses the highest electrical conductivity of
any element, the highest thermal conductivity and reflectivity of any metal.
The metal occurs naturally in its pure, free form (native silver), 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. More
abundant than gold, silver metal has in many premodern monetary systems
functioned as coinable specie, sometimes even alongside gold. In addition,
silver has numerous applications beyond currency, such as in solar panels,
water filtration, jewelry and ornaments, high-value tableware and utensils
(hence the term silverware), and also as an investment in the forms ofcoins and
bullion.

Silver is used industrially in electrical contacts and conductors, in
specialized mirrors, window coatings and in catalysis of chemical reactions.
Its compounds are used in photographic film and X-rays. Dilute silver nitrate
solutions and other silver compounds are used as disinfectants and
microbiocides (oligodynamic effect), added to bandages and wound-dressings,
catheters and other medical instruments.
