Silver

Basic Facts
Silver is a metallic chemical element with the chemical symbol **Ag** and it's atomic number is 47.Silver's location on the periodic table is in group 11 and period 5. It has the highest electrical conductivity of any element as well as the highest thermal conductivity of any metal. Silver is the best reflector of visible light. Silverware, jewelry, and other decorative items are made from an alloy of silver, sterling silver. Photographic films and paper are made from silver nitrate. Silver is slightly harder than gold and is a transition metal. It is a very precious metal because it is of high value. Most silver is produced as a secondary product of copper, gold, lead, and zinc. Silver has the highest electrical conductivity of any element. They are doing further research to find clinical ways in which silver can be useful. Silver is very ductile and malleable. It also has the highest electrical conductivity of all the metals. Silver metal dissolves in nitric acid and produces silver nitrate. Silver nitrate can be used as the yellow-stain in stained glass, as an antiseptic, or to compose other silver compounds.

History
has been used for thousands of years, with many different uses, its value has always been ranked second, right behind gold. The word 'silver' has appeared in Anglo-Saxon in many different spellings. The Chemical symbol for silver, Ag, is from the latin word for silver, from the indo-European root, meaning 'white' or 'shining'. This metal has ben widely known and used since ancient times, and it was even mentioned in the book of genisis. Recorded uses of silver to prevent infection dates to ancient Greece and Rome, and it was soon re-discovered in the middle ages, when it had many different uses. During WWII, 13,540 tons of silver were used in electromagnets to enrich uranium. This was because there was a shortage of copper during the war.

__ SOME USES __ Dentistry Silver can be alloyed with mercury, tin and other metals at room temperature to make amalgams that are widely used for dental fillings. To make dental amalgam, a mixture of powdered silver and other metals is mixed with mercury to make a stiff paste that can be adapted to the shape of a cavity. The dental amalgam achieves initial hardness within minutes but sets hard in a few hours.

Ways to finish Silver Jewelry 1. expensive jewels are polished by machines because they are sensitive. 2. to get the black antique look you can put a nickel plating. sometime this is illegal. sold in italy. 3. oxidize the silver to make it black. pricing is similar to the machine polished ones. 4. the most expensive is using Rhodium. its actually more expensive that silver and doesn't tarnish, it makes silver look better and appreciated the value.

In 1980, the silver price rose to a peak for modern times of US$49.45 per troy ounce (ozt) due to market manipulation of Nelson Bunker Hunt and Herbert Hunt. Inflation adjusted to 2011 this is approximately U$D150 per troy ounce. Some time after Silver Thursday, the price was back to $10/ozt From 2001 to 2010, the price moved from $4.37 to $20.19 (Average London US$/oz). According to the Silver Institute, silver's recent gains have greatly stemmed from a rise in investor interest and an increase in fabrication demand. In late April 2011, silver reached an all-time high of $49.76/ozt.
