What is Silver?

Name

Greek: άργυρος árguros, Latin: argentum, both from the Indo-European root *h₂erǵ- for “grey” or “shining” The word “silver” appears in Anglo-Saxon in various spellings, such as seolfor and siolfor. The chemical symbol Ag is from the Latin word for “silver”, argentum (compare Greek άργυρος, árgyros). The name originates from the Old English Anglo-Saxon word ‘seolfor’ meaning silver. The Symbol Origin is from the Latin word ‘argentum’ meaning silver. Argentina was named for this precious metal. Silver was once referred to as one of the ‘Noble Metals’ which also included Gold and Platinum.

History

The ancient ‘Metals of Antiquity’ together with their approximate dates of discovery and use are Gold (6000BC), Copper (9000BC), Silver (4000BC), Lead (6400BC), Tin (3000BC), Iron (1500BC) and Mercury (1500BC).

The crescent moon has been used since ancient times to represent silver.

Geology

occurs naturally in its pure, free form (native silver), as an alloy More abundant than gold, alloy with gold (electrum), Ores include argentite (Ag2S), chlorargyrite (AgCl) which includes horn silver, and pyrargyrite (Ag3SbS3

Peru, Bolivia, Mexico, China, Australia, Chile, Poland and Serbia Cannington (Australia), Fresnillo (Mexico), San Cristobal (Bolivia), Antamina (Peru), Rudna (Poland), and Penasquito (Mexico)

The metal is primarily produced as a byproduct of electrolytic copper refining, gold, nickel, and zinc refining, and by application of the Parkes process on lead metal.

Silver is found in small quantities in the uncombined state; usually, however, it occurs in combination with sulphur, either as the sulphide (Ag2S) or as a small constituent of other sulphides, especially those of Lead and copper. It is also found alloyed with Gold. Silver occurs in nature to some extent in the free state, but is usually found as a sulphide. Silver ore is easy to reduce.

Silver ore is found in native form. The other principal sources of silver are copper, copper-nickel, gold, lead and lead-zinc ores. Found in Canada, Mexico, Peru, Australia and the USA.

Silver can be obtained from pure deposits, from silver ores such as argentite (Ag2S) and horn silver (AgCl), and in conjunction with deposits of ores containing lead, gold or copper.

Monetary

premodern monetary systems functioned as coinable specie

Industrial

solar panels, water filtration, jewelry and ornaments, high-value tableware and utensils industrially in electrical contacts and conductors, in specialized mirrors, window coatings and in catalysis of chemical reactions. photographic film and X-rays. disinfectants and microbiocides

Silver is used in food coloring; it has the E174 designation Traditional Indian dishes sometimes include the use of decorative silver foil known as vark dragée are used to decorate cakes, cookies, and other dessert item food additive is not approved in the United States.

highest electrical conductivity of any element, highest thermal conductivity and reflectivity of any metal. the highest thermal and electrical conductivity of the metals.

Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Silver is classified as a “Transition Metal” which are located in Groups 3 – 12 of the Periodic Table. Nearly 75% of all the elements in the Periodic Table are classified as metals. Elements classified as Transition Metals are generally described as ductile, malleable, and able to conduct electricity and heat.

It is not acted upon by water or air, but is quickly tarnished when in contact with sulphur compounds, turning quite black in time.
