Chapter 12, Problem 56GQ

Interpretation Introduction

Interpretation:

The overall structures of molecular, network and amorphous solids differ each other has to be explained.

Concept introduction:

Molecular solid:

Molecular solids melt closer to 300 °C, which is can be either ductile or brittle. Many molecular solids have a large band gap between the valence band and conduction band.

Network solid:

Network solid has very high melting point, which are very hard.

Network solid doesn't conduct electricity, which are insoluble in water and organic solvents.

Amorphous solid:

In these solids particles are randomly arranged in three dimensions, does not have sharp melting points, which forms due to sudden cooling of liquid.
