Experiment to describe reactivity of a given set of metals.

Experiment to Determine the order of Reactivity for a given set of Metals
Prediction
I predict that the order of reactivity for the given set of metals will be Sodium, Magnesium, Zinc, Iron, and Copper. With copper being the least reactive.
The Reason for my Prediction
Iron is used for ships hulls and nails so it can't be very reactive. Copper is used in electrical equipment so that too can't be very reactive. And sodium reacts very violently with water so that is very reactive and magnesium can't be as reactive as sodium.
Apparatus and Reactunts
Samples of: Zinc foil, Copper foil,…
