Which is more reactive, Sodium or Magnesium?

Sodium is a more electropositive metal which means that it "hates" electrons more than magnesium therefore it needs less energy to chuck electrons than magnesium does ... Those are the main factors that explain why sodium metal is more reactive than magnesium metal

Answer: Sodium is more reactive.
