This diagram covers Simple Molecular Structures within Simple Molecules for GCSE Chemistry. Revise Simple Molecules in Bonding & Structure for GCSE Chemistry with 20 exam-style questions and 21 flashcards. This topic appears less often, but it can still be a useful differentiator on mixed-topic papers. It is section 1 of 11 in this topic. Focus on the labels, the relationships between parts, and the explanation that turns the diagram into an exam-ready answer.

🔬 Simple Molecular Structures

Four simple molecular models: water (H2O, bent), carbon dioxide (CO2, linear), methane (CH4, tetrahedral), and ammonia (NH3, pyramidal) shown as ball-and-stick models

Figure 1: Molecular models of common simple molecules — H₂O, CO₂, CH₄, and NH₃. Each molecule has strong covalent bonds WITHIN it but only weak intermolecular forces BETWEEN molecules.
