Understading the theory of corrosion (Experiment)

Level 2

A student read in a book while studying chemistry that silver corrodes after some time after reacting with external constituents.

He decided to try it himself. He places a bright and shiny piece of silver (big piece to observe the tarnish cleanly) in the open (where it can get contact with the air moisture and other things) for about a month and forgets about it. After a month he gets back to the place to observe his sample. What would have happened to the silver?

Details and Assumptions :

1) Air contains nitrogen, oxygen, carbon dioxide and other constituents.

\ce{Ag}_{2}\ce{O}

(Silver Oxide) It loses it's lustre. But it still looks like silver

Well the silver piece got stolen, hence he saw nothing there.

What is this bro, you told that this was not a troll problem and even specifically made comments not to think this is a troll question.

Fortunately, i read in the link that sulphur is a must and i assumed ideal atmosphere with no sulphur at all, and hence thought no change and answered nothing

I had exactly same logic .As i read "for about a month and forgets about it. After a month he gets back to the place to observe his sample. What does he observe :" it struck in my mind It is stolen.

Also the bright and big gives the hint
