What is Silver?
Silver is a chemical element with the chemical symbol Ag and atomic number 47. A soft, white, lustrous transition metal, it possesses the highest electrical conductivity of any element and the highest thermal conductivity of any metal. Element Symbol
• Ag
• Silver, Symbol
Element Name
• Silver
Atomic Mass
• The atomic mass is 107.8682
Atomic Number
• The atomic number is 47

The Story of its Discovery
Unknown since prehistoric time. Man learned to separate silver from lead as early as 5000 B.C. A precious shiny grayish- white metal, the chemical element of atomic number. In Anatolia
(modern Turkey), Asia minor and Greek islands. Around 40005000 B.C. Silver is found in its pure form in nature. It also can be found alloyed with gold and other metals or in the presence of minerals, such as argentite and chlorargyrite.
Physical Properties
• Physical Properties: Silver is a soft white metal with a shiny surface. It is the most ductile and most malleable metal.
Ductile means capable of being drawn into thin wires.
Malleable means capable of being hammered into thin sheets. Silver has two other unique properties. It conducts heat and electricity better then any other element. It also reflects light very well.
Chemical Properties
• Chemical Properties: Silver is a very inactive metal. It does not react with oxygen in the air under normal circumstances. It does react slowly with sulfur compounds in the air, however.
The product of this reaction is silver sulfide (Ag2s), a black compound. The tarnish that develops over time on silverware and other sliver-plated objects is silver sulfide.

Uses of the Element and/or its
Compounds
About 10 percent of silver produced in the Untied States is used in coins, jewelry, and artwork. Other objects use much more of the silver metal, however. About half of the silver produced in the Untied States goes into the photograph film. Pure silver is first
