GCSE Chemistry - Diamond & Graphite - Structure | Properties (2026/27 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ ** WHAT'S COVERED ** 1. Allotropes of Carbon Definition of allotropes as different structural forms of the same element. Introduction to diamond, graphite, graphene, and fullerenes. 2. Structure and Properties of Diamond A giant covalent structure. Each carbon atom is covalently bonded to four other carbon atoms. Forms a regular, rigid 3D lattice. Properties: very strong, high melting point, and does not conduct electricity as there are no free electrons. 3. Structure and Properties of Graphite A giant covalent structure arranged in layers. Each carbon atom is bonded to three other atoms, forming hexagonal rings. Layers are held by weak forces and can slide over each other, making graphite soft. Has a high melting point due to strong covalent bonds within the layers. Conducts electricity and heat due to delocalised electrons between the layers. 4. Graphene and Fullerenes A brief introduction to graphene as a single layer of graphite. A brief mention of fullerenes. ** CHAPTERS ** 0:00 Introduction 0:20 What are Allotropes? 0:46 Diamond Structure & Properties 1:37 Graphite Structure & Properties 2:54 Graphene and Fullerenes ** PLAYLISTS **    • KS3 Biology      • KS3 Chemistry      • GCSE Maths (9-1)      • GCSE Biology (9-1)      • GCSE Chemistry (9-1)      • GCSE Physics (9-1)      • A-Level Biology   #GCSE #Chemistry #study #revision #school #exam #AQA #OCR #Edexcel #IGCSE
