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.
But alkali metals gives of electron to its stable form easily than other metals, and other atoms like the halogens, oxygen, sulfur, nitrogen will receives the electron easily, and energy is produce greatly. But why cesium is the most reactive of the alkali metals? This is because cesium have the biggest atomic radius in the alkali metal, it loses electron easily, while lithium is the less reactive metal in the alkali metal, because it has the smallest atomic radius and it grabs electron the tightest so it doesnât loses electron easily.
