AQA Combined Science – Chemistry FT
Bonding, Structure and the Properties of Matter
Chemical Bonds, Ionic, Covalent and Metallic
1) State the two types of element which ionic bonding occurs between
1 Marks
Video Mark Scheme
2) Two atoms of sodium can bond ionically with one atom of sulphur to form sodium sulphide (Na2S). Describe what happens, in terms of electron transfer, when this occurs. Give the formulae of the ions formed
5 Marks
Video Mark Scheme
3) The dot-and-cross diagram below shows a molecule of hydrogen sulphide (H2S). Explain how this type of bonding has occurred
3 Marks
Video Mark Scheme
4) Explain why many covalent molecules, such as hydrogen sulphide, are gases at room temperature
2 Marks
Video Mark Scheme
5) By contrast, metals are almost always solid at room temperature. Their metallic bonding means that they have very different physical properties. Unlike covalent molecules, metals can conduct electricity. Explain how electricity is conducted in a metal, making reference to its structure and bonding
