SUPPLEMENTARY

5. Describe the formation of ionic bonds between ions of metallic and non-metallic elements, including the use of dot-and-cross diagrams

6. Explain in terms of structure and bonding the properties of ionic compounds:
(a) high melting points and boiling points
(b) good electrical conductivity when aqueous or molten and poor when solid
