To know ionic bonding as electrostatic attraction between positive and negative ions, and the construction of ‘dot-and-cross’ diagrams 2. To explain solid structures of giant ionic lattices are a result of oppositely charged ions strongly attracted to each other in all directions 3. To link the structure and bonding of ionic compounds on their physical properties including melting and boiling points, solubility and electrical conductivity in solid, liquid and aqueous states **Lesson 4: Covalent and Dative Covalent Bonding 1. To know covalent bonding as electrostatic attraction between a shared pair of electrons and the nucleus 2.

To know what a dative covalent bond is 5. To construct dot and cross diagrams of molecules and ions to describe dative covalent bonding **Lesson 5: Simple and Giant Covalent Structures 1. To describe the structure of simple and giant covalent compounds 2. To explain how the structure and bonding of simple and giant covalent compounds link to their different physical properties 3. To evaluate the potential applications of covalent structures based on their physical properties (stretch & challenge) **Lesson 6: Metallic Bonding and Structure 1. To describe the structure of metals 2. To explain metallic bonding as strong electrostatic attraction between cations and delocalised electrons 3. To explain the physical properties of giant metallic structures **Lesson 7: Shapes of Molecules and Ions 1. To determine the number of bonding pairs & lone pairs in a molecule or ion 2. To recall the shapes and bond angles of molecules and ions with up to six electron pairs surrounding the central atom 3.

To construct diagrams to illustrate the 3D shapes of molecules and ions **Lesson 8: Electronegativity and Bond Polarity 1. To define the term electronegativity 2. To explain the trend in electronegativity down a group and across a period 3. To explain what a polar covalent bond is bond and to illustrate this type of bond in a molecule **Lesson 9: Polar and Non-Polar Molecules 1. To describe the difference between polar and non-polar molecules 2. To explain why non-polar molecules can contain polar bonds 3. To predict whether molecules are polar or non-polar **Lesson 10 : Intermolecular Forces (Part 1) 1. Understand intermolecular forces based on induced-dipole interactions and permanent dipole-dipole interactions 2. Explain how intermolecular forces are linked to physical properties such as boiling and melting points 3. Compare the solubility of polar and non-polar molecules in polar and non-polar solvents **Lesson 11 : Intermolecular Forces (Part 2) 1. To understand hydrogen bonding as intermolecular forces between molecules containing N, O or F and the H atom of –NH, -OH or HF 2. To construct diagrams which illustrate hydrogen bonding 3. To explain the anomalous properties of H2O resulting from hydrogen bonding ***Declaimer: Please refrain from purchasing this popular resource for an interview lesson or a formal observation. This is because planning your own lessons including using your own lesson PowerPoints is a fundamental skill of a qualified/unqualified teacher that will be reviewed during these scenarios outlined above***
