Understading the theory of corrosion (Experiment)

Level pending

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?

Bad smell in the area Black layer of \(\ce{AgS}\) (Silver Sulfide) White layer of \(\ce{Ag_{2}}\ce{CO_{3}}\) (Silver Carbonate) Nothing Silver turns into liquid silver It loses it's lustre. But it still looks like silver Brown layer of \(\ce{Ag}_{2}\ce{O}\) (Silver Oxide) That silver piece shines even more
