why does copper have positive electrode potential? it has same inthalpy of ionisation(2) as nickel(-2121) so it should also have a negative value

Expert Answer:

Copper has lower tendency than hydrogen to form ions, so if the standard hydrogen electrode is cconnected to the copper half-cell, the copper will be relatively less negative. The copper electrode has relatively lower number of electrons. so it has positive electrode potential.
