• Thermodynamic properties of dilute aqueous solutions are influenced by the interactions between ions and water molecules as well as the change of the water structure around the ion. To obtain hydration energies of monoatomic ions and local water structures around the ions, we make use of the discrete-continuum method. The calculated values for the hydration energies of ions are in good agreement with experimental values. The hydration energies of monoatomic cations can be qualitatively correlated with the sum of the successive ionization potentials from its atomic state to the ionic state. From their correlations, we can classify various ions as three groups. It is also found that the main factors which determine the stability of water structures around the ions are the charges and dimensions of ions.
