Chapter 11, Problem 11.108QP

Interpretation Introduction

Interpretation:

Aluminium, Silicon, Phosphorous and Sulphur forms fluoride.  The kind of solid that formed by fluoride has to be identified.

Concept introduction:

Types of solid

• Molecular solid
• Metallic solid
• Ionic solid
• Covalent network

Molecular solid:

A solid which consist of atoms or molecule thought intermolecular force.

Metallic solid:

The solid which consist of metal atom held together by metallic bonds.  Metallic bonding is chemical bond formed by attraction between cation of metal and the surrounding sea of electrons.

Ionic solid:

A solid which consist of anions and cations held together by ionic bond (electrical attraction of opposite charges).

Covalent network:

A solid that involves atoms held together by great network or shackles by covalent bonds.

Diamond and graphite are great example.
