Key knowledge:
• common properties of ionic compounds (brittleness, hardness, high melting point, difference in electrical conductivity in solid and liquid states) with reference to their formation, nature of ionic bonding and crystal structure including limitations of representations
• experimental determination of the factors affecting crystal formation of ionic compounds
• the uses of common ionic compounds.
