Silver has been known since ancient times and who and when it was discovered is not known.

Silver is mined underground and is usually mixed with other elements. They wash all the dirt off of it at the mine site and send it away.

Some physical properties of silver is that its color is silver and it is slightly harder then gold.

Chemical reactions of silver are silver is stable in clean air under normal conditions, silver does not react with clean water, and AgF2 is formed when silver and fluorine combine.

Silver is found in many compounds such as silver fluoride, silver chloride, silver bromide, silver iodide, and silver oxide.

Chemical equations- 2Ag+H2SO4 produces Ag2SO4+H2, Ag+F2 produces AgF2

Uses for silver are rings, gun powder, and cars.

Unusual facts- possesses the lowest contact resistance, silver iodide is used to produce clouds that produce rain, and highest electrical and thermal conductivity of all metals.
