Diamond Metallic bonding Metallic bonding Number of covalent bonds from each Describe metallic bonding C2 Bonding, structure carbon and the properties of Melting point is low / high / very high matter Why doesn’t it conduct What bonds together? electricity? AQA Trilogy There are several ways to represent Graphite Why are most metals: Draw a diagram to show why alloys are covalent bonds: Number of covalent bonds from each solid at room temperature? harder than pure metals carbon Melting point is low / high / very high Good conductors of electricity and heat Why does it conduct electricity? The repeating unit of poly(ethene) is Write about the uses of Draw a diagram to show why most shown below. What is the molecular Fullerenes like Bucky balls metals are malleable formula of poly(ethene) and nanotubes Predict the state of: o Bromine at room temperature (25 C) Nitrogen at room temperature (25oC) o Oxygen at – 220 C o The reason that most polymers are solid Name the process: Draw particle diagrams to show a solid, Ethanol melts at -114 C and boils at o at room temperature is: Solid liquid liquid and a gas 78 C. Predict the state at: Liquid gas o Gas liquid -150 C solid liquid gas Liquid solid o 0 C o 25 C o 100 C
