Ions and ionic bonds

1 Describe the formation of positive ions, known as cations, and negative ions, known as anions

5 Describe the giant lattice structure of ionic compounds as a regular arrangement of alternating positive and negative ions

2 State that an ionic bond is a strong electrostatic attraction between oppositely charged ions

3 Describe the formation of ionic bonds between elements from Group I and Group VII, including the use of dot-and-cross diagrams

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

4 Describe the properties of ionic compounds: (a) high melting points and boiling points (b) good electrical conductivity when aqueous or molten and poor when solid
