Question

Quizplus · Accepted Answer

Crystalline solids are defined by having atoms or molecules arranged in a long-range repeating pattern, while amorphous solids lack this ordered arrangement. Glass, while often mistaken for an amorphous solid, is actually a type of non-crystalline solid with a unique atomic arrangement. Table salt, on the other hand, is an example of a crystalline solid with a highly ordered arrangement of Na+ and Cl- ions. Option D is incorrect as amorphous solids are still composed of atoms or molecules with no significant portion of empty space.
