Introduction

Atoms usually bond together so that they can obtain a full outershell of electrons. There are different type of bonding which can occur between atoms of different elements.
 * Bonding **

The different types of bonding are:
 * Ionic bonding
 * Covalent bonding
 * Metallic bonding

The type of bonding that two atoms form depends on their **electronegativity values**. //(these will all be discussed in detail in the following lessons) //
 * If the two atoms have very different electronegativity values, then they form an ionic bond.
 * If the two atoms both have quite high electronegativities then they form covalent bonding.
 * If the two atoms both have low electronegativities then they form metallic bonding.
