Crystal lattice types
WebOct 16, 2024 · Crystal lattices can be classified as either monatomic or polyatomic. This classification is based on the kind of atoms present in the face within a lattice structure. If there is only one... WebLattices also determine the shape that mineral crystals grow in and how they break. For example, the right angles in the lattice of the mineral halite (Figure 1.4) influence both the shape of its crystals (typically cubic), and the way those crystals break (Figure 2.8).
