Metals get tarnished when exposed due to the formation of which layer on their surface
1 Answer
abhay gupta
Answer:
metal reacts with non metals mainly oxygen to form a thin layer of metal oxide on its surface which is basic in nature. this is called corrosion and the tarnished metal is said to be corroded. this layer protects further corrosion.
thank you.
