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.
Rating Newest Oldest. Best Answer: Alkali metals are reactive because of their ionization energies. Ionization energy is the energy required to remove one electron from the atom. Alkali metals have only one valence electron, and if you'll recall all atoms want to be noble gases, i.e. they want full valence shells.ating Newest Oldest.
