ChemistryStructure and bondingGCSEAQA Created by: HarrietCreated on: 26-11-14 20:46 Explain the process of ionic bonding When atoms lose or gain electrons to form charged particles which are then strongly attracted to each other 1 of 6 What structure do ionic compounds have? Giant ionic lattices 2 of 6 Why do salt crystals tend to be cuboid in shape? A single crystal of sodium chloride (salt) is one giant ionic lattice 3 of 6 Main properties of ionic compounds high melting points, high boiling points, carry electric current when molten and dissolved in water 4 of 6 Why do ionic compounds carry an electric current when molten? When ionic compounds melt, the ions are free to move 5 of 6 Why do ionic compounds have a high boiling and melting point? There is a strong attraction between the ions so it takes a large amount of energy to overcome the attraction. 6 of 6
