Due to HYDROGEN SULFIDE
Explanation:
Silver becomes black because of hydrogen sulfide (sulfur), a substance that occurs in the air. When silver comes into contact with it, a chemical reaction takes place and a black layer is formed. ... The oxidation of silver jewelry is a sign that it is really silver. Other (noble) metals oxidize differently.
