4. In a crystal, the particles are arranged in

A ball-like shapes of varying sizes

B sheets or layers that can separate from one another

C an orderly, repeating, three-dimensional pattern

D a random pattern that does not repeat

The correct answer is C

In a crystal, the particles are arranged in an orderly, repeating, three-dimensional pattern.

Option C

Explanation:

Solid crystal particles can be ions, molecules or atoms, based on the material kind. The three-dimensional solid crystal system is called the crystal lattice. The crystals are divided into general categories according to their shape.

The crystal is characterized by faces that intersect at specific angles characteristic of this material. Crystal is a material in which particles get arranged in an ordered, repeatable, three-dimensional way. Means, a solid contains an atomic patterns that is uniformly repeated in three dimensions.
