Lewis Diagrams

Lewis Dot Diagrams show us the bonding electrons in atoms and molecules. We use our knowledge of the Periodic Table to work out how many bonding (valence) electrons an atoms has.

Once we work out how to draw Lewis Diagrams for atoms, we try to put them together to represent the bonding in molecules.

Some molecules do not seem to work. This is when we need to move lone pairs of electrons between atoms to create double (or triple) bonds.
