Chapter 12.5, Problem 2RC

Interpretation Introduction

Interpretation:

The particular solid type should be identified.

Concept introduction:

Metallic solid:

Metallic solid is high melting points, range from soft and malleable to very hard, which are good conductors of electricity.

Ionic solid:

Ionic solid has very high melting points

Ionic solids are brittleness and poor conductors in the solid state.

Molecular solid:

Molecular solids melt closer to $\text{300 °C}$, 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.

Alloy solid:

Alloy solid is high melting points, which are good conductors of electricity.
