Resolvation Energy ~ Desolvation EnergyNa (OH2)6+= hydration shell (6 H2O needed to stabilize Na+)Within the K+Ion Channel only:Resolvation Energy <<< Desolvation Energy**When two K+occupy adjacent sites, electrostatic repulsion forces them apart. Thus, as a K+enters the selectivity filter from one side, repulsive force from the next K+ entering the filter pushes the first ion through the pore and out the other side, namely out of the cell.
