Which of the following statements is true for Amorphous solids?
Correct answer: B. They are isotropic
- A. They possess symmetry
- B. They are isotropic
- C. They are anisotropic
- D. They cleave along a particular direction
- E. They have a definite shape
Explanation
Amorphous solids are isotropic because they show thermal and optical properties, same in all directions. They do not possess symmetry, can cleave randomly, and do not have a definite shape.

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.
