• When a metal is exposed to the atmosphere in the presence of moisture, it reacts with Oxygen and water vapor present in the air to form its oxide which tarnishes the metal surface.
• The natural process, which converts a refined metal to a more stable form, such as its oxide, hydroxide, or sulphide is known as Corrosion.
• The process of corrosion of Iron articles in the presence of damp air is known as rusting.

Hence, The process of coating one metal with a thin layer of another metal is called electroplating.
