WebMay 9, 2024 · Much of this potential energy difference is because the valence electrons of metallic Zn are higher in energy than the valence electrons of metallic Cu. Because the Zn (s) + Cu 2+ (aq) system is higher in energy by 1.10 V than the Cu (s) + Zn 2+ (aq) system, energy is released when electrons are transferred from Zn to Cu 2+ to form Cu and Zn 2+.
