- (A), (C), (D) only
- (C), (D) only
The Correct Option is B
Solution and Explanation
Crystalline materials are characterized by a highly ordered and repeating arrangement of atoms in a lattice. This gives rise to:
• Sharp melting point and boiling point: Due to the uniform arrangement and bonding, crystalline materials have a defined melting and boiling point.
• Periodic arrangement of atoms: This defines the crystalline nature, with atoms arranged in a repeating pattern.
Isotropic properties, meaning properties are the same in all directions, are characteristic of amorphous materials.
