Aluminum is more reactive than iron, yet it is used today for a variety of applications in which iron would corrode (cans, rain gutters, the reason for the corrosion durability of aluminum is that all aluminum products are treated with a plastic coating. aluminum does not react with oxygen. aluminum does not undergo oxidation. very unreactive aluminum oxide forms a thin layer on aluminum.

The reason for the corrosion durability of aluminum is that: D. Very unreactive aluminum oxide forms a thin layer on aluminum.

Aluminum is a chemical element that is found in group (3) of the periodic table and as such, it has 3 electrons in its outermost shell.

Therefore, aluminum has three (3) valence electrons in the outermost shell of its atomic nucleus. Also, its chemical symbol is Al.

In comparison with iron (Fe), aluminum is more chemically reactive but it is widely used for a variety of applications (cans, rain gutters, roofing sheets, etc.) in which iron (Fe) would easily corrode.

Basically, the main reason for the corrosion durability of aluminum is that a thin layer of very unreactive aluminum oxide are formed on the surface of aluminum.

In conclusion, aluminum is protected from corrosion due to the formation of very unreactive aluminum oxide as a thin layer on aluminum.

Aluminum is more reactive than iron

but it forms Al-oxide, that form a thin layer on the surface of Al, and protect Al from reaction with water.

Very unreactive aluminum oxide forms a thin layer on aluminum.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
