Chemical Bonding and Molecular Structure

Calculation of lattice enthalpy and Concept of electronegativity

Lattice Energy :
The amount of energy released during the formation of 1mole of ionic crystal from its constituent gaseous ions is called lattice energy
u \propto \frac{q_{1}q_{2}}{r^{+} + r^{-}}

Born Haber cycle(Calculation of lattice energy)

Hydration energy :
The process in which cation and anion are surrounded by H2O molecules is called hydration energy.
 If HE > LE soluble
    HE < LE insoluble
