structure of a noble gas (Group 0). The electron transfer during the formation of an ionic compound can be represented by a dot and cross diagram, eg for sodium chloride: The charge on the ions produced by metals in Groups 1 and 2 and by non-metals in Groups 6 and 7 relates to the group number of the element in the periodic table. WS 1.2 Students should be able to translate data between diagrammatic and numeric forms (MS 4a). MS 5b 4.2.1.3 An ionic compound is a giant structure of ions. Ionic compounds are held together by strong electrostatic forces of attraction between oppositely charged ions. These forces act in all directions in the lattice and this is called ionic bonding. The structure of sodium chloride can be represented in the following Students should be familiar with the structure of sodium chloride but do not need to know the structures of other ionic compounds. Students should be able to: deduce that a compound is ionic from a diagram of its structure in one of the specified forms describe the limitations of using dot and cross, ball and stick, two and 1 Extended writing: describe the bonding in the sodium chloride lattice using the correct terms, eg electrostatic forces of attraction. Model the sodium chloride lattice using molecular model kits.
