Magnesium
Sodium is highly reactive to water
Magnesium is not a noble metal. Magnesium is highly reactive, a noble metal is the exact opposite.
Sodium, aluminum, and magnesium are metals. For metals, reactivity decreases as you go from left to right across the periodic table. The least reactive of those three is therefore aluminum.
Sodium is highly reactive with water and dissolves in an exothermic reaction.
sodium is more reactive than magnesium!

Sodium chloride is not highly reactive.
Sodium is more reactive than either magnesium or iron.
Magnesium is one of the more reactive metals; it rarely exists in nature elementally.
