Naf lattice enthalpy
Witryna24 sty 2024 · Lattice enthalpy of an ionic solid is the minimum thermal energy required to completely convert one mole of that ionic solid to isolated gaseous ions. Here … Witrynaaccording to me MgO has more lattice energy that LiF. The lattice energy of an ionic compound is the enthalpy change which occurs when one mole of an ionic compound dissociates into its ions in gaseous state. More ionic is a compound, stronger would be the ionic bond and more would be the lattice enthalpy .
