Electronegativity may be described as the power of an atom to attract electrons to itself in a chemical bond. It is the most important chemical parameter in calculating the type of
Thermodynamic properties: Salts dissolve producing both cations and anions. It means that it is impossible to measure thermodynamic data for individual ion type. The solvation
