What are the characteristic properties of crystalline solids, particularly regarding the arrangement of particles and their melting points?
Understand the Problem
The question pertains to the properties of crystalline solids, specifically their arrangement of particles and their melting points. It seeks to understand whether this arrangement is regular or irregular, and how the properties vary based on direction.
Answer
Regular arrangement, sharp melting points, anisotropy.
Crystalline solids have a regular, repeating arrangement of particles and sharp melting points. They often exhibit anisotropy, meaning their properties differ in various directions. This structure leads to well-defined melting points and the ability to diffract X-rays.

More Information
Crystalline solids, due to their structured lattice, have unique properties such as anisotropy, which means their mechanical or optical properties vary with direction.
Tips
A common mistake is confusing crystalline solids with amorphous ones, which do not have a definite structure or melting points.
