Why does alluminium react with water?

Answer 1

Al ions are very small due to their high charge-surface area ratio , that's why they're so small. these ions gather at surface of the metal and react with O2 in air or water forming Be(O2)2 compound, making a shield to protect other atoms from the o2 in air or water. That's why aluminum foil doesn't react with water. Same applies to Be.

Answer 2

Aluminum reacts with water to form aluminum hydroxide and hydrogen gas. This reaction occurs because aluminum is higher than hydrogen in the reactivity series, leading to the displacement of hydrogen from water.

Answer 3

no. alluminium is coated in a thin layer of alluminium oxide preventing rust
