Statement - I : ${\mathrm{E}}_{{\mathrm{Cu}}^{+2}/\mathrm{Cu}}^{\mathrm{o}}$ is positive.
Statement - II : Enthalpy of atomization of Cu is highest of 3d series.

Copper is the only metal in 3d series having positive ${\mathrm{E}}_{{\mathrm{M}}^{+2}/\mathrm{M}}^{\circ }$ value because the sum of enthalpies of sublimation and ionization is not balanced by hydration enthalpy.

Enthalpy of atomization of Vanadium is highest of 3d series.
