'giant' arrangement of ions is repeated // 'lattice' arrangement is regular (not random) 14 of 19 What kind of melting and boiling points do ionic compounds have? high 15 of 19 Why do ionic compounds have high melting and boiling points? large amount of energy is needed to break the electrostatic attraction between ions 16 of 19 Why can ionic compounds dissolve easily in water? water is slightly charged - water molecules form electrostatic attraction with ions in the compound and pull them apart 17 of 19 Why can't solid ionic compounds conduct electricity? ions are not free to move 18 of 19 Why can ionic compounds conduct electricty in a molten state? ions are free to move 19 of 19
