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 discoloration.

Tarnishing of a silver spoon is a chemical change. It occurs when the silver reacts with sulfur compounds in the air or food, forming silver sulfide. This chemical reaction alters the composition of the spoon, resulting in the tarnished appearance.
Silver sulfide (Ag2S) is a black compound that forms when silver reacts with sulfur. It is commonly found in tarnished silver objects.
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.The tarnish, also called 'patina' is mostly sulphide and oxide of both metals.
Tarnished silver can usually be easily cleaned using silver polish or a mixture of baking soda and water. However, if the tarnish is severe or the item is valuable, it may be best to seek professional cleaning or restoration services to avoid damaging the silver. Regularly polishing and storing silver properly can help prevent tarnishing in the future.
It depends on the age of the silver, if it is more than 4 years old it will be dull.

Yes. Tarnished silver is caused by the reaction of the silver with oxygen.

Tarnished silver is not a compound. Tarnishing occurs when silver reacts with sulfur compounds in the air or on the skin, forming silver sulfide on the surface of the metal. Silver itself is an element.
compound of silver and oxygen.
Silver utensils can become tarnished when exposed to sulfur-containing foods like egg yolks. The sulfur in the egg yolk reacts with the silver to create silver sulfide, resulting in the tarnished appearance. To prevent tarnishing, it is best to avoid prolonged contact between silver utensils and sulfur-containing foods.

Rubbing it gently with sodium bicarbonate.
Sulfur gas (and other gases) can cause silver to oxidize (loose electrons). The silver looses it's shine and becomes tarnished.
