Tarnish is a thin layer of corrosion that forms over copper,
brass, silver, aluminum, magnesium and other similar metals
as their outermost layer undergoes a chemical reaction.
Tarnish does not always result from the sole effects of
oxygen in the air. For example, silver needs hydrogen sulfide
to tarnish, although it may tarnish with oxygen over time.



** The Wiki does not actually say that *silver oxide* is formed on bare silver, in air at room temp.

Other Google references say that in rare cases, silver chloride can form but make no mention of silver oxide.
