A-Level Chemistry Lessons - February, 2026

We’ll revisit the core principles of bonding and structure, covering electron shells and orbitals, the shapes of orbitals, and electron configuration. We’ll then move on to the shapes of molecules and finish by exploring intermolecular forces and how they influence physical properties.

We’ll explore periodicity and the trends across the Periodic Table, focusing on ionisation energy and oxidation numbers using key graphs. We’ll also examine trends in melting and boiling points, before consolidating understanding of ionic, covalent, metallic, and dative bonding and how these bonding types determine material properties.

We’ll explore reactivity trends and key reactions with oxygen, water, and acids, linking these to trends in melting and boiling points. The focus will be on understanding solubility patterns of hydroxides, sulfates, and nitrates, and applying this knowledge to difficult exam questions.
