Options:
  • A Copper readily gains electrons to form M2+ions.
  • B Copper has a strong affinity for oxygen.
  • C Copper has a high value of atomization enthalpy and low hydration enthalpy. Thus, as a result, the overall effect E⊖(M2+/M) for copper is positive.
  • D Copper has a higher ionization energy than most other metals
