Verified step by step guidance1
Understand the difference between crystalline and amorphous solids. Crystalline solids have a well-ordered, repeating arrangement of atoms or ions, while amorphous solids lack this long-range order.
Identify the substances listed: Plastic, Glass, Sodium chloride (NaCl), and Rubber. Consider their typical structural characteristics.
Recall that Sodium chloride (NaCl) is an ionic compound that forms a regular, repeating lattice structure, which is characteristic of crystalline solids.
Recognize that Plastic, Glass, and Rubber are generally amorphous materials without a long-range ordered structure, so they do not exhibit a crystalline appearance.
Conclude that Sodium chloride (NaCl) typically exhibits a crystalline appearance due to its ionic lattice structure.
