How do some reactive metals avoid serious corrosion damage and how?
Some reactive metals avoid complete corrosion by the formation of a stable oxide on their surface. Oxygen oxidizes the metal on the surface of the metal, forming a metal oxide. In some cases, this oxide does not easily separate from the rest of the metal, and is inert under the conditions present. In this case, the rest of the metal avoids corrosion, as oxygen cannot penetrate through the oxide layer to react further.
