Overview: Bonding and Structure
This is an overview of Topic 6: Bonding & Structure. It includes ionic and covalent bonding, dot and cross diagrams , dative covalent bonding, shapes of molecules, electronegativity and more.
Ionic Bonding
This video defines ionic bonding and shows how to represent the electrons of the constituent ions in the compound using dot and cross diagrams.
Properties of Ionic Compounds
This video explains the properties of ionic compounds including electrical conductivity, melting and boiling, formation of giant lattices and more.
Covalent Bonding
This video explains what covalent bonding is, octet rule and provides examples when octet rule is not observed.
Coordinate/Dative Covalent Bonding
This video explains the difference between covalent bonds and dative covalent bonds including common examples.
Shapes of Molecules Introduction
This video introduces the different shapes of simple molecules and includes an acronym to help answer typical exam questions involving shapes of molecules.
Shapes of Molecules: 3&4 Electron Pairs in the Valence Shell
This video explains shapes and bond angles in molecules with 3 and 4 pairs of electrons in the valence shell providing examples.
Shapes of Molecules: 5&6 Electron Pairs in the Valence Shell
This video explains of the shapes and bond angles in molecules with 5 and 6 pairs of electrons in the valence shell providing examples.
Shapes of Molecules: The Effect of Lone Pairs in the Valence Shell

Electronegativity and Polarity
This video introduces the concepts of electronegativity and polarity using a helpful tug of war analogy.
Identifying Polar and Non-Polar Molecules
This video explains the importance of symmetry in determining whether a molecule is polar or non-polar.
Intermolecular Forces Introduction
This video explains what intermolecular forces are and relative strength of this force compared to ionic, covalent and metallic bonds.
Types of Intermolecular Forces
In depth video explaining the three types of intermolecular forces; induced dipole-dipole, permanent dipole-dipole and hydrogen bonding and relative strengths.
Anomalous Properties of Water
