The solids in which the molecules or ions are arranged in a regular repetitive manner are called:
Correct answer: D. Crystals
- A. Amorphous solids
- B. Glassy solids
- C. Polymers
- D. Crystals
Explanation
Crystals are characterized by a precise and repeating lattice structure that extends in all three spatial dimensions, resulting in a highly ordered arrangement of particles. This is contrasted with amorphous solids and glassy solids, which do not exhibit such order. Polymers may show some degree of order but are not typically organized in a repeating three-dimensional lattice like crystals.

About Crystalline Solids
Crystalline solids contain particles arranged in a regular repeating lattice described by a unit cell. Their study includes coordination number, packing efficiency, density, anisotropy, cleavage, polymorphism and common crystal systems, along with ionic, molecular, covalent network and metallic crystals. Crystalline order differs from the random arrangement of amorphous solids.
