There it occurs as a by-product of gold mining. Physical Properties-Critical temperature: No Data Found. Liquid Range:1200.07 k, Superconduction Temperature: No Data Foun. Color is silver, and is metallic. Chemical Properties-Silver will not react with any acid, and halogens. For example; Ag(s) + F2(g) → AgF2(s) [brown], also an inactive metal Minerals- [|argentite] and [|chlorargyri]te Compounds-halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides) Ores-igneous and sedimentary Most common chemical reactions-silver sulfide (Ag 2 S), a black compound, and Ag(s) + F2(g) → AgF2(s) [brown], Industrial uses- Jewlery,silverware,and clothing Commercial uses-Photography, Music, and Medical Cost of Value-$541.12. Facts: 1.Silver kills bacteria by chemically affecting the cell membranes, breaking them down. 2.Today, Peru and Mexico are the largest producers of silver. 3.Research has shown that the catalytic action of silver, in concert with oxygen, provides a powerful sanitizer, that virtually eliminates the need for the use of corrosive chlorine. 4.In fourteen languages, the words for silver and money are the same. 5.One out of every seven pairs of prescription eyeglasses sold in the U.S. incorporates silver. 6.Argentina was named from Argentum, the element of Silver's Latin name. 7.Throughout history, more people have used silver for money than have used gold. 8.In the earliest Egyptian records, Silver was considered more precious than Gold.
