Corrision is the phenomenon happened here.It is a process by which metals react with moisture and other elements to form their respective oxides and forms a outer surface area.
Silver turned into black and so it reacted with sulfur and the compound name is Silver sulfide(AgS)
Copper reacted with oxygen and turned into green to form copper oxide(CuO)
hope it helps....
