Structure controls properties
Structure controls properties

A solid's physical properties depend on what particles it contains and what attractions hold those particles together. A crystal lattice is a regular, repeating three-dimensional arrangement of ions, atoms or molecules.
Step-by-step lessons on AQA A Level Chemistry Bonding and physical properties. Each one builds up to exam-style questions. Build confidence with atomic structure, bonding and moles calculations early on, since these underpin the more demanding organic mechanisms, equilibrium and practical-analysis topics that dominate Year 2.
