@Eliza.
The most electronegative elements are nonmetals.

cuso4+fe = cu+feso4.
Ferrous sulphate formula feso4.
Sodium sulphate formula na2so4.
Silver sulphate formula ag2so4.
Mercury (hg) is not metal is acid.
So answer is fe.

According to metal activity series, Fe is more reactive than Cu that means no reaction should take place and a less reactive element cannot replace a more reactive element and hence no reaction should take place. Then how come Cu replaces Fe?

Iron is less reactive than Cu according to the reactivity series table.
That is why iron is used to recover in the copper sulphate solution.

Refer the electrochemical series position of both the copper. So the answer is iron.

Wonderful study on research about fe.

If Fe is more reactive than Cu then Na is also more reactive than Cu. So why cannot we use Na to get Cu from copper sulphate solution.
