Fe, it because of electrochemical series.

But the molecular formula of iron is Fe.

@Dolly,
Sodium is not used for recovering of cu because cu present in aqueous solution, if sodium is as cathode then it react with water to form sodium hydroxide, hydrogen instead to act as cathode.

Fe reduces easily copper sulphate and forms ferrous sulphate due to its reducing property when compared with copper.

The solution first at colour blue. After reacting it with Fe we get green colour now.

Iron(Fe) is more reactive than Copper(Cu). So Iron displaces Copper from Copper sulfate(CuSO4) to form Iron sulfate(FeSO4).

FE is iron then what is need?

I Think Fe (Ferrum) will work best because it is not very reactive and yet it can displace copper from its sulphate. Sodium (NA or Natrium) can as well be used.

Cu is biggest molecule.

As the fe and cu both lying in the same group. And although the electronegativity of fe is higher than cu.
