It is unknown exactly who discovered Silver, however, it has been known since ancient times. Evidence shows that man has known how to separate silver from lead form as early as 3000 B.C.
 * How, when and who discovered it- **

<span style="font-family: 'Britannic Bold','sans-serif'; font-size: 16px;">Silver is mined, and is usually found combined with sulfur, arsenic, antimony, or chlorine. The mines are located in various countries, such as Australia, Mexico, Peru, and Canada. In order for silver to be in its pure form to be produced and sold, the elements that it’s found with must be extracted. These elements are extracted by using chemicals to separate the different elements. The silver mixed with other elements, is first crushed into smaller pieces, then a cyanide solution is added. After that’s finished, fine zinc dust is used to precipitate the metal from the solution. Lastly, the silver is filtered off, melted, and is then ready to be made into bullion bars and sold.

<span style="font-family: 'Britannic Bold','sans-serif'; font-size: 16px;">Silver is a very inactive metal, and does not react with oxygen. However, it does react with sulfur compounds in the air very slowly. On silverware, there is a tarnish, which is just silver sulfide. Silver doesn’t react readily with water, acids, etc. and it will not burn except as silver powder.

<span style="font-family: 'Britannic Bold','sans-serif'; font-size: 16px;">Silver is a soft, white metal with a shiny surface. It’s the most ductile and most malleable metal. It also conducts heat and electricity better than any other element, and is also a very good light reflector.

<span style="font-family: 'Britannic Bold','sans-serif'; font-size: 16px;">-Silver is generally found in ore deposits and in those ores are lead-zinc, copper, and gold-silver.

<span style="font-family: 'Britannic Bold','sans-serif'; font-size: 16px;">Silver will tarnish because of the compounds in the atmosphere. <span style="font-family: 'Britannic Bold','sans-serif'; font-size: 16px;">It will also react with sulfuric acid.
