Lewis Dot Diagrams
The Lewis dot diagram shows the number of valence electrons in an atom in an almost 'box like' fashion around the symbol

Multiple Choice
How many valence electrons does Aluminum Have?
7
Lewis Dot Diagrams for Ions
Metals lose their valence electrons and form positive ions; cations
Nonmetals gain electrons and form negative ions; anions
8
Lewis Dot Diagram for Ionic Compounds
Shows the charges on the ions in brackets
9
Structure of Ionic Compounds
The + and - ions in Ionic compouds are held together by strong 'electrostatic attractions'
The compound will always be electrically neutral
10
Formation of Ionic Bond
The positive CATION and negative ANION are held together in a crystaline lattice structure
The exact structure and shape will depend on the size of the cation and anion
11
Formation of Ionic Bond
The formation of an ionic bond is an EXOTHERMIC process which means that energy is released

Oxidation Numbers
The oxidation number indicates the number of electrons lost or gained.
The Metals lose their valence electrons
The Nonmetals gain electrons to get to 8
The group the element is in in the periodic table will tell you how many electrons will be lost or gained.
