Which one of the following is the best example of an amorphous solid?
Correct answer: B. Glass
- A. Diamond
- B. Glass
- C. Sodium chloride
- D. Potassium Bromide
Explanation
Glass is the standard example of an amorphous solid, with no long range order in its particles, so it softens over a range of temperature instead of melting sharply. Diamond, sodium chloride and potassium bromide all have regular crystalline lattices.

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.
