WebMay 30, 2024 · Graphite is unusual because it is a non-metal that conducts electricity. Why is graphite weaker than diamonds? This means that each carbon atom has a ‘spare’ electron (as carbon has four outer electrons) which is delocalised between layers of carbon atoms. These layers can slide over each other, so graphite is much softer than diamond. WebMay 27, 2024 · A pencil contains graphite, which is a stacking of graphene layers. The layers are held together by single-electron bindings between carbon atoms while the …

WebBoth have a giant covalent structure. Graphite has layers of carbon atoms that are held together by weak intermolecular forces. The layers can slide over each other easily. Each carbon only forms 3 covalent bonds to create a layer. In Diamond each carbon atom is strongly (covalently) bonded to 4 others. The structure is tetrahedral. how far is cha am from bangkokWebCopper is malleable because the layers of atoms in the lattice can slide over each other. Copper atoms can be oxidised to form copper ions by losing electrons. Copper has a high melting point because of the strong electrostatic attraction between the positive ions and the ‘sea of electrons’. hi gear triple picnic tableWebThe forces between the layers in graphite are weak.
