Silver (Ag from Lat. Argentum) – an element of the 11th group (according to the outdated classification – a secondary subgroup of the first group), the fifth period of the periodic table of chemical elements DI Mendeleev, with atomic number 47.
Simple substance silver is a malleable, ductile noble metal of silver-white color. The crystal lattice is face-centered cubic. Melting point – 962 ° C, density – 10.5 g / cm³.
Jewellery and silverware
The major use of silver besides coinage throughout most of history was in the manufacture of jewellery and other general-use items, and this continues to be a major use today. Examples include table silver for cutlery, for which silver is highly suited due to its antibacterial properties. Western concert flutes are usually plated with or made out of sterling silver. In fact, most silverware is only silver-plated rather than made out of pure silver.
In medicine, silver is incorporated into wound dressings and used as an antibiotic coating in medical devices. The silver ion is bioactive and in sufficient concentration readily kills bacteria in vitro. Silver ions interfere with enzymes in the bacteria that transport nutrients, form structures, and synthesise cell walls.
Silver-containing brazing alloys are used for brazing metallic materials, mostly cobalt, nickel, and copper-based alloys, tool steels, and precious metals. The basic components are silver and copper, with other elements selected according to the specific application desired: examples include zinc, tin, cadmium, palladium, manganese, and phosphorus. Silver provides increased workability and corrosion resistance during usage.
The word “silver” appears in Anglo-Saxon in various spellings, such as seolfor and siolfor. A similar form is seen throughout the Germanic languages. The chemical symbol Ag is from the Latin word for “silver”, argentum, meaning “white” or “shining”. Silver was one of the seven metals of antiquity that were known to prehistoric humans and whose discovery is thus lost to history.
