no, potassium.
Sacrificial protection is basically attaching a piece of metal that is more reactive that iron to the object made of iron. This more reactive metal, commonly magnesium or zinc, will corrode in the place of iron. That is, the more reactive metal will feed the iron with electrons each time the iron is oxidised to form iron ions, thus reverting it to iron once again instead of letting it become iron hydroxide (rust). Thus, the more reactive metal is sacrificed for the iron.
Francium is the most reactive metal.

Thus, the more reactive metal is sacrificed for the iron. This is a common method used to prevent rusting of large steel objects such as underground pipes, oil tankers or ships.n
magnesium is an alkaline earth metal. silver, copper, lead, zinc, and iron are transition metals. alkaline earths are naturally more reactive then transition metals.

Iron will react with calcium oxide as iron is more reactive than calcium, therefore calcium (which is the more reactive metal) will displace calcium (the less reactive metal) to form a compound. This is called a displacement reaction.
Electroplating is the coating of a reactive metal with a less reactive metal. This allows the reactive metal take longer to corrode. E.G.: Coating steel or iron with gold or silver
all the metals are reactive but the most reative metal is iron.
Lithium is the most reactive.
Potassium is the most reactive. It is in the 1st group. It is an alkaline metal.

Because iron is a more reactive metal than copper.
Sacrificial protection is only effective if the metal used for sacrificial protection is more reactive than Iron in the reactivity series. Since gold is one of the least reactive metals in the reactivity series, it would not get oxidized in the place of Iron. A more reactive metal than Iron, e.g. Zinc, is used as the Zinc metal would oxidize in the place of iron, thus preventing Iron from rusting.
