Chapter 1, Problem 4RQ

(a)

Interpretation Introduction

Interpretation:

The description “It has a regular pattern” refers to a crystalline solid or amorphous solid has to be given.

Concept Introduction:

Crystalline solid:

The solids in which the constituent particles of matter are arranged and organized in a specific manner are called crystalline solid.  These solids contain crystals in their structure and each crystal has definite geometry.  Almost all solids fall in the category of crystalline solids including metallic elements iron, silver and copper and non-metallic elements phosphorous, sulphur and iodine.

Amorphous solid:

The solids in which the constituent particles of matter are arranged in a random manner are called amorphous solids.  It is a non-crystalline solid with no proper arrangement of atoms in the solid lattice.  The most common examples of amorphous solids are glass.
