Aluminum is reactive and will react spontaneously with water and/or air to form aluminum oxide. Aluminum oxide, Al2O3, forms a stable passive layer that protects aluminum from corrosion or further oxidation. This layer is about 4 nm thick and will provide corrosion protection as long as this oxide layer is stable.
The stable ion of aluminum is Al 3+, which means it has three fewer electrons. The aluminum atom has shed its outer shell of 3s2 3p1 and has an electron configuration equa â¦ l to that of Neon, or 1s2 2s2 2p6.
