Oxygen.<\/p>\n<p>Silver is a relatively stable metal, but it can corrode in the presence of oxygen. This process is called oxidation, and it results in the formation of silver oxide, which is a black or brown powder.<\/p>\n<p>Oxygen is a gas that is present in the air. It is also found in water and in many other substances. When silver is exposed to oxygen, the oxygen atoms react with the silver atoms to form silver oxide. This reaction is accelerated by heat and by the presence of other chemicals, such as acids.<\/p>\n<p>Silver oxide is a relatively harmless substance, but it can discolor silver jewelry and other objects.
