One element, two structures
One element, two structures
Diamond and graphite are both giant covalent structures. In diamond, carbon atoms are joined to their neighbours by strong covalent bonds in a three-dimensional network. In graphite, strong covalent bonds join carbon atoms in continuous two-dimensional layers, while weak forces act between the layers.
Step-by-step lessons on Edexcel GCSE Chemistry 2.5.3 Giant covalent structures: diamond and graphite. Each one builds up to exam-style questions. Nail the core quantitative topics — moles, balancing equations and calculations — early on, since they underpin higher-tier questions across every paper and topic.
