Does the ordering of activity series Mg, Zn, Fe, Cu, Ag agree with
the ionization energies of the elements? Why or why not?
selecuul UI e vunum 14. Since the activity series describes the propensity for a metal to lose electrons one might think that ionization energies could predict the activity series.
