The first thing we should understand is that the same thermodynamic change in energy should result whether the reaction were to take place in the gas phase (Born-Haber cycle) or in solution. Different maturities but same tenor to obtain the yield. go across a row of the periodic table or down a column. Dispersion forces are present between all molecules, whether they are polar or nonpolar. From experimental studies, it has been determined that if molecules of a solute experience the same intermolecular forces that the solvent does, the solute will likely dissolve in that solvent. As the solvent molecules and the ions interact, the potential energy is indeed lowered. Covalent bonds usually occur between nonmetals. increased from Na+ to Na2+ or Na3+.

Still, if we consider all the parameters for polarity for NaCl, it indeed is a polar molecule. Sodium Chloride (formula: NaCl), also known as Salt, is a crystalline compound.The abbreviation NaCl is derived from the chemical symbols of Sodium (Na) and Chloride (Cl). are no simple, discreet molecules of sodium chloride (or of other Ionic bonds usually occur between metal and nonmetal ions. This is a principle of conservation of energy, Hess's Law. There are negative charges on the Chlorine atom and positive charges on the Sodium atom in this molecule. The formula NaCl is a formula unit which NaCl. The electrostatic forces between the positive cations and anions are strong. By the way, I think you will also find a good correlation of heterolytic solution phase bond strength with bond length (actually, ion gap). What this means is that polar compounds dissolve polar compounds, nonpolar compounds dissolve nonpolar compounds, but polar and nonpolar do not dissolve in each other.
