Aluminum metal undergoes the same basic corrosion process that iron does yet it does not decompose as rapidly.Why?

Question

Quizplus · Accepted Answer

The aluminum oxide that forms on the surface of the metal does not flake off like rust does on iron. Instead, it forms a stable and protective layer that prevents further oxidation, thus slowing down the corrosion process. This is why aluminum does not decompose as rapidly as iron even though they both undergo the same basic corrosion process.
