Crystalline Solids
Crystalline solids have a regular, repeating arrangement of atoms or molecules. The atoms are arranged in a face-centered or body-centered crystal lattice. This structure gives crystalline solids high strength, hardness, and electrical conductivity.
Examples:
Diamond
Metals like copper and aluminum
Salt
Amorphous Solids
Amorphous solids do not have a regular, repeating arrangement of atoms or molecules. Instead, the atoms are arranged randomly or in a disordered pattern. Amorphous solids have low strength, flexibility, and thermal conductivity.
Examples:
Glass
Rubber
Plastic
Polyurethane foam
