1. General flow

   Sublimation of cation (if necessary) Or, if necessary Fusion (melting) -> Vaporization (boiling) ionization(s) of cation sublimation of anion (if necessary) Or, if necessary Fusion (melting) -> Vaporization (boiling) Bond dissociation of anion (typically needed) Electron affinities of anion (depends on both charge and number of anion atoms - gets all anion atoms to a certain charge - like ionizations) Lattice energy

2. Enthalpy (heat, ΔH\Delta HΔH ) of reaction

   ΔH=reactants−products\Delta H=\text{reactants} - \text{products}ΔH=reactants−products , in KJmol\frac{\text{KJ}}{\text{mol}}molKJ​
