• Lattice Energy is the energy required to combine gaseous ions into a solid, crystalline structure.
• Lattice Energy can be approximated using the equation for ionic bond energy.
The higher the ionic bond energy, the greater the lattice energy.
where radius is the period number
Which compound in each of the following pairs has the larger lattice energy? Note: Mg2+ and Li+ have similar radii; O2– and F– have similar radii. Explain your choices.
(b) LiF or MgO
