Explanation:

Background. When silver is exposed to sulfur-containing gases in the air, it discolours and then darkens as it reacts with the gas to form a surface layer of tarnish. ... If a silver object is to be kept from tarnishing, it must be protected from sulfur-containing gases

Answer:

WHEN THE SILVER ARTICLES COME IN THE CONTACT WITH AIR (oxygen) THE LAYER OF SILVER OXIDE GET COATED ON IT WHICH MAKES IT BLACK IN COLOUR AND THE SILVER ARTICLES LOSSES ITS SHINE PERMANENTLY .

as silver is the least 2nd reactive elements so it reacts while taking much time. ...

SILVER + OXYGEN = SILVER OXIDE

Ag + O2 --------->Ag2O
