Silver(I) sulfide, Ag 2 S, is very readily formed from its constituent elements and is the cause of the black tarnish on some old silver objects. It may also be formed from the reaction of hydrogen sulfide with silver metal or aqueous Ag + ions.
Silver has 28 radioisotopes (radioactive forms), although most are very unstable and have very small half-lives (under 3 minutes). Silver is slightly harder than gold. The first silver coins were used by the Lydians in 700 BC. The coins were actually an alloy of gold and silver. Other Great Discoveries: Who Discovered Gold. Who Discovered Bromine Sources: Silver occurs native and in ores incuding argentite (Ag 2S) and horn silver (AgCl). Lead, lead-zinc, copper, copper-nickel, and gold ores are other prinicipal sources of silver. Commercial fine silver is at least 99.9% pure. Commercial purities of 99.999+% are available. In fact, Ag is short for argentums, the Latin word for silver. The word "silver" is from the Anglo-Saxon word seolfor.
