Answer . It happens with exposure to air and certain chemicals. The silver atoms combine with oxygen to form a layer of silver oxide, which is what causes the discolorat…ion. . See Related Links . See the Related Links for "How to clean and polish silver" to the bottom for the answer.
Silver tarnishes from reacting with Oxygen in the air (The stuff we breathe, if you don't know, I highly doubt you don't know) thus forming tarnish.
yes it can tarnish very well if not protected
exposure to substances which react with the surface of the metal, usually sulphur. Sterling silver is .925 (925%) pure silver. The other .75 is made up of an alloy consistin…g mainly of copper which oxidizes over time. When copper is exposed to oxygen, it darkens and eventually turns green. Sterling silver doesn't usually turn green but will turn almost black if not protected. Fine silver or .999 silver doesn't tarnish. Argentium silver is a new type of sterling silver that is tarnish-resistant. Only certain chemicals will tarnish Argentium but it will not tarnish from oxidation. Some metals that contain little to no silver are branded with names that make it seem like real silver. One of these metals is nickle silver, which doesn't contain any silver at all.
Yes, it happens, unfortunately.
Silver tarnish occurs when silver turns black, caused by oxidationwhen it is exposed to the air. Tarnish can be removed by rubbingthe silver with polish and a soft cloth.
The tarnishing of silver is a chemical reaction in which oxygen and hydrogen sulfide in the air is reacting with (oxidizing) metallic silver to form silver sulfide, Ag 2 S. Th…is reaction is dependent upon moisture, and occurs much more rapidly under humid conditions.
Good question! I know that there are so many different things that can tarnish silver. I believe the main cause for tarnishing silver is sulfur that is found in many lotions a…nd cleaners.

why silver jewellery tarnish with lime?
Pure silver can tarnish but not as easily as Sterling Silver.
Tarnished silver is the same as oxidized silver.
Yes ! Sincerely: " LIVING LIFE INTERPRISES ".
supplement Pure silver tarnishes much less then sterling silver, which contains about 7% of copper. The copper is added to improve the hardness in for example, table use. T…he tarnish, also called 'patina' is mostly sulphide and oxide of both metals.
Silver tarnish is silver that has reacted with the air to form Silver Oxide, AgO, under certain conditions, and it is black in color. Silver Nitrate, AgNO3, has been used to d…evelop photographic pictures, years ago. Now it has been replaced with other chemicals. In the old days, a Photographer who used to develop pictures, when done, would go outside into the sunlight and his arms would instantly turn black. You've probably seen old pictures of this. There are cleaners out there that will remove the tarnish, though the silver may never look the same as it did. For this reason, cleaning collectible silver coins will instantly cause their value to diminish or even become worthless - the color of the silver has changed, there is minute scratches on the surface of the coin, and Coin Dealers don't like them - the coin has lost its eye appeal.
