@Eliza.
The most electronegative elements are nonmetals.

I hold Fe as the answer; since Fe is found above Cu in the electrochemical series, it will displace Cu from CuSO4 to give FeSO4 and metallic Cu.
We talk of the electrochemical or reactivity series instead of electromagnetic series.
Thanks for your various proposed answers.
Fe + CuSO4 --------- = FeSO4 + Cu.

It is the most electronegative element.

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.

Any element higher than copper in the electrochemical series table will displace copper i.e. not copper itself.

Reactivity of Fe is more than copper.

Fe lies above cu in metal activity series so it simply displaces cuso4.

It's simple displacement reaction.
cuso4+fe ->feso4+cu.
cuso4+fe ->feso4+cu.

Why Fe has more reduction power then Cu ?
Fe _ [Ar]18 3d6 4s2 & Cu_ [Ar]18 3d10 4s1.
So the reduction power of Fe is more then cu, as reduction power is nothing but ability to gain electron.
