Uses: Silver 's main use is to be made into jewelry but it is very soft so it can get dent easily. It was put into coins in ancient times, used to make silverware, and is included in high capacity batteries. It is also put into dental alloys, electrical contacts and brazing alloys and making soder. Silver Iodine (AgI) is used for causing clouds to produce rain. Silver Nitrate (AgNO3) is very light sensitive and can be used to make photographic films and papers. Sterling silver is also used for jewelry but is better than silver because it is harder so it is able to withstand an occasional blow without denting.

Factual Information: Silver is considered to be a Precious metal and a Nobel metal along with Platinum and Gold but it the least expensive as them. It is a very soft metal which makes it ductile and malleable. Pure silver is the highest electrical and thermal conductor of all metals, it is also the best reflector of light. Silver isn't very reactive because it doesn't oxidize when heated, dissolve in most mineral acids or react with non-polluted air or water. Silver only tarnishes ( turns into black Silver Sulfide), this happens when Silver is in contact with hydrogen sulfide gas that is in polluted air. Tarnishing occurs mostly in Industrial cites and on the tip of the utensil from some foods such as egg that has hydrogen sulfide in it. Sterling silver is composed of 92.5% silver and 7.5% copper. Equation of Tarnishing Silver: Silver + hydrogen sulfide + oxygen = Silver sulfide + water 4Ag(s) + 2H2S(g) + O2(g) = 2Ag2S(s) + 2H2O
Background Information: Silver's name origin is from Anglo-Saxon. Its atomic symbol (Ag) is from the word Argentium which is Latin for silver. Its discovery date is unknown but is traced all the way back to ancient times. Because silver is not very reactive and the silver compounds are rarely produced it was found in its pure form. Because it wasn't mixed with any other elements it was easy for the Egyptians to use it over 5,000 years ago.		Sources: Silver can be found in argenite, horn silver, lead, lead-zinc, copper, gold, and copper-nickel ores.
Glossary: Alloy: A solid solution of metals or nonmetals dissolved in metals. Nobel metals: Gold, Silver, and Copper. Precious metals: Valuable metals such as Platinum, Gold and Silver. Ore: Any natural combination of minerals that a metal can be extracted. Oxidize: To increase the positive valence or decrease the negative valence of an element
