Covalent vs Ionic structures 5.0 / 5 based on 4 ratings ? ChemistryStructure and bondingGCSEAQA Created by: a.bellCreated on: 26-10-15 20:23 Why do ionic compounds have high melting and boiling points? There are strong forces of attraction between the oppositely charged ions. 1 of 7 How is an ionic compound arranged? In a giant lattice structure. 2 of 7 Can ionic compounds conduct electricity? Only when dissolved or molten because the ions are then free to move. 3 of 7 Why are most covalent compounds gases? They have very low boiling points as there are weak intermolecular forces. 4 of 7 Can covalent compounds conduct electricity? No, there are no free electrons. 5 of 7 Name two giant covalent substances... Diamond and graphite 6 of 7 What are the 5 properties of a giant covalent substance? Extremely hard but brittle, unreactive when solid, doesn't dissolve in water, extremely high melting points, doesn't conduct electricity. 7 of 7
