Rust Zinc

zinc and aluminum will not rust, corrode, but do. explain why?

the question of corrosion of metals

Corrosion is an oxidation process of metals in the presence of water. For iron this process is called oxidation. The oxidation of aluminum and zinc wrt to corrosion. The oxidation of iron and carbon steel is the most common form of corrosion. The effects of corrosion are often (well, essentially always) undesirable. Oxide is generally formed on the surface of metal, and does not adhere to the surface. When rust flakes off, the underlying metal is exposed to further corrosion (a process called pitting), and finally, the structural integrity of the metal breaks.
