This exam focus covers Exam Focus within Metallic Bonding for GCSE Chemistry. Revise Metallic Bonding in Bonding & Structure for GCSE Chemistry with 22 exam-style questions and 21 flashcards. This is a high-frequency topic, so it is worth revising until the explanation feels precise and repeatable. It is section 10 of 12 in this topic. Treat this as a marking guide for what examiners are looking for, not just a fact list.
🎯 Exam Focus
Frequently Examined
Metallic bonding questions are common, particularly comparing metals to ionic compounds:
- Explain how metals conduct electricity — delocalised electrons free to move (2 marks)
- Explain why metals are malleable/ductile — layers of ions slide, electron sea maintains bond (2 marks)
- Compare metallic and ionic conductivity — metals conduct as solids; ionic only when molten/dissolved (2-3 marks)
- Predict relative melting points of two metals — higher charge / more electrons = higher MP (2 marks)
The critical phrase for conductivity answers is: "delocalised electrons are free to move and carry charge."
Edexcel 1CH0: Examined in Paper 1 (1CH0/1). Edexcel metallic bonding questions ask students to explain electrical conductivity (delocalised electrons), malleability (layers slide without breaking bonds), and compare metal melting points in terms of ion charge and electron density. Comparing metallic bonding conductivity to ionic compounds (solid vs molten) is a common 3-mark question. In Edexcel-style questions, the command word "Suggest" appears frequently — use your chemistry knowledge to apply to an unfamiliar context.
