**Crystalline solids** typically have:
ANo definite arrangement of particles
BLong-range order, sharp melting points, anisotropic properties (except cubic)
CAlways isotropic properties
DParticles in random arrangement
Answer & Solution
Correct answer: B. Long-range order, sharp melting points, anisotropic properties (except cubic)
Crystalline solids: regular, periodic arrangement over long range; sharp melting point; anisotropic properties (except cubic). Examples: NaCl, diamond, graphite, metals.
