Lesson Worksheet: Lattice Energies of Ionic Solids Chemistry • 10th Grade

In this worksheet, we will practice defining the lattice energy of an ionic solid and describing how its value varies with ion size and charge.


The lattice energy of LiF is 1,023 kJ/mol, and the LiF distance is 201 pm. MgO crystallizes in the same structure as LiF but with a MgO distance of 205 pm. Which of the following values most closely approximates the lattice energy of MgO?


The formation of an ionic lattice from a metal and a nonmetal can be divided into four stages:

  1. Conversion of elements to gaseous atoms
  2. Removal of electrons from metal atoms
  3. Addition of electrons to nonmetal atoms
  4. Formation of a lattice from gaseous ions

Which two stages are typically exothermic?

  • A1 and 3
  • B2 and 4
  • C1 and 2
  • D2 and 3
  • E3 and 4
