Silver

Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes alongside gold:[4] while it is more abundant than gold, it is much less abundant as a native metal.[5] Its purity is typically measured on a per-mille 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.

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. Silver is used in

• Solar Panels,
• Water Filtration,
• Ornaments,
• High-value tableware and utensils (hence the term silverware),
• Electrical contacts and conductors,
• Specialized mirrors,
• Window coatings,
• Catalysis of chemical reactions,
• As a colorant in stained glass and in specialised confectionery.

Its compounds are used in photographic and X-ray film. Dilute solutions of silver nitrate and other silver compounds are used as disinfectants and microbiocides (oligodynamic effect), added to bandages and wound-dressings, catheters, and other medical instruments.
