Cambridge AS Level Chemistry: Chemical Bonding — Ionic, Covalent & Coordinate Covalent
Master chemical bonding for Cambridge AS Level Chemistry — from ionic lattices to covalent molecules and coordinate bonds — with clear theory, worked examples, and exam-focused practice.
Perfect for: Students studying Cambridge AS Level Chemistry (9701), AS/A Level chemistry students globally following similar syllabuses (e.g. Edexcel, OCR), and teachers looking for structured, syllabus-mapped bonding resources.
Chemical bonding is the backbone of AS Level Chemistry, yet it's one of the topics where students lose the most marks in Cambridge exams. Misunderstanding why atoms bond, how to draw dot-and-cross diagrams correctly, or when to apply coordinate bonding concepts can cost you grades — not because you haven't studied, but because the subtle distinctions were never made crystal clear.
This school strips the topic down to its fundamentals and rebuilds it the right way. You'll start with a solid understanding of ionic bonding — how ions form, how lattices are structured, and how to explain physical properties using bonding arguments the examiner wants to see. From there, you'll move into covalent bonding, mastering dot-and-cross diagrams, electronegativity, bond polarity, and the shapes of molecules using VSEPR theory. Finally, you'll tackle coordinate (dative covalent) bonding — one of the most misunderstood concepts at this level — with concrete, memorable examples like the ammonium ion and the Al₂Cl₆ molecule.
Every lesson is built around the Cambridge AS Level syllabus and exam command words. You won't just understand the chemistry — you'll know exactly how to express it in a way that earns full marks. Worked exam questions, annotated diagrams, and targeted activities make this course as practical as it is conceptual.
Whether you're preparing for your first sitting of the Cambridge AS exam, catching up after a shaky start to the year, or consolidating your knowledge ahead of A Level, this school gives you the structured, exam-ready foundation you need to walk into the exam hall with confidence.
What you'll be able to do
- Explain ionic bond formation in terms of electron transfer and describe the structure of ionic lattices
- Draw accurate dot-and-cross diagrams for ionic, covalent, and coordinate covalent species
- Apply VSEPR theory to predict and justify the shapes and bond angles of simple molecules and ions
- Define and apply the concepts of electronegativity and bond polarity to determine molecular polarity
- Identify and explain coordinate (dative covalent) bonds in species such as NH₄⁺, H₃O⁺, CO, and Al₂Cl₆
- Relate the physical properties of substances (melting point, conductivity, solubility) to their bonding and structure
- Interpret and answer Cambridge-style exam questions on chemical bonding using precise scientific language
- Distinguish confidently between ionic, covalent, and coordinate covalent bonding in unfamiliar contexts

Hi, and welcome to the school! I'm passionate about making Cambridge AS Level Chemistry accessible, logical, and — dare I say it — enjoyable. Chemical bonding is a topic I've seen trip up even the brightest students, not because the chemistry is impossibly hard, but because the fine details that examiners care about are rarely explained with enough precision in a typical classroom. That's exactly why I built this course. I've spent considerable time analysing Cambridge mark schemes and examiner reports to understand precisely where students drop marks, and I've designed every lesson to close those gaps. My teaching approach is simple: understand the concept deeply first, then learn how to express it in the language the examiner rewards. I hope you find this school genuinely useful — let's get those marks up together.
