Silver has been known since ancient times. The origin of the name comes from the Latin word argentum meaning silver. It is a silvery-ductile and malleable metal, stable in water and oxygen. Silver reacts with sulfur compounds to form black sulfides. Silver is found in ores called argentite (AgS), light ruby silver (Ag3AsS3), dark ruby silver (Ag3SbS3) and brittle silver. Pure silver is too soft to be used in jewelry, so it's commonly alloyed with other metals (typically copper) to prevent scratching and distortion. The light sensitive silver halides (AgCl, AgBr, AgI) are used to make photographic film and photographic paper. Silver is the best conductor of heat and electricity of all known metals. The price of 99.9 % pure silver shot is 406.30 € for 250 g.
