Silver is derived from Anglo-Saxon word seolfor. Chemical symbol of Silver comes from the Latin word (argentums). According to archaeological evidences, people of different civilizations have been using this metal (silver) for at least 5000 years. Silver can be found in pure deposits which are from silver ores for example argentite (Ag2S) and horn silver (AgCl), and in conjunction with deposits of ores containing lead, gold or copper. Silver and its compounds have many uses for ages. Pure silver is considered as the best conductor of heat and electricity of all metals discovered till now. Sometimes, it is used in making solder, electrical contacts, printed circuit boards and in many other things. Silver is also known as the best reflector of visible light, but to save it from tarnishing, sliver mirrors must be given a protective coating for protection. It has also been used for many years to create coins. However, other metals are typically introduced and they have taken its place in making coins. Sterling silver which is an alloy contains 92.5% silver. It is used for making silverware, jewelry and other decorative things. High capacity batteries are also made from silver and zinc and silver and cadmium. Sliver nitrate (AgNO3) is known as light sensitive and is widely used to prepare photographic films and papers. Silver iodide (AgI) is applied to seed clouds to produce rain.
