Lesson 11
Structure of crystal lattices
Lattice energy
Objectives
Understand ionic compound of crystal lattice
Understand the definiton of lattice energy
Calculate lattice energy of ionic compound
The Crystalline State
Single crystals comprise an innite array of
ions, atoms, or molecules, known as a
crystal lattice.
For crystals comprising ions and metal
atoms, the lattice may be thought of as
regular packing of hard spheres.
The Unite Cell
The smallest repeating unit of an extended
crystal lattice is known as the unit cell,
which governs the symmetry and structure
of the overall bulk crystal.
