Higher values tend to reflect lower solubilities, smaller radii, and higher charges.  
Its value is proportional to the Madelung constant, which is related to the crystal structure.  Higher values tend to reflect lower solubilities, smaller radii, and higher charges.  Directly immeasurable, this quantity, represented by U, can be calculated by an indirect process that uses Hess's Law.  FTP, identify this thermodynamic quantity, measured by the Born-Haber cycle, which is the amount of energy required to separate a crystal into its constituent gaseous ions.
