Silver is a transition metal, and transition metals are less reactive than metals of the s and p blocks. Also, kinetically, oxygen is slow in reacting with other elements. Therefore, silver and oxygen doesn't combine easily.
But silver is quite sensitive to sulphur. It reacts with sulphur-containing compounds present in air forming black silver sulphide, Ag2S. That is why silver wares and jewelry gradually get tarnished on continuous exposure to air.
