3 of 13© Boardworks Ltd 2012 Different compounds There are four different types of compounds. These are: The type of bonding in a compound affects its physical properties, including melting and boiling points, solubility and electrical conductivity. Compounds that contain ions are called ionic compounds. The positive and negative ions are strongly attracted to each other. This electrostatic attraction is called ionic bonding. ionic compounds simple molecular covalent compounds giant molecular covalent compounds metallic compounds.

5 of 13© Boardworks Ltd 2012 What is an ionic lattice? In an ionic compound, millions and millions of ions are packed together in a regular lattice arrangement, joined by strong ionic bonds between oppositely-charged ions. The structure of the ionic lattice affects the properties of the ionic compound. The ionic lattice will continue to build in this way until there are no more ions left to add. This forms a giant 3D structure called an ionic lattice.
6 of 13© Boardworks Ltd 2012 Ionic compounds such as sodium chloride, form crystals, with a cubic shape. This is due to the regular structure of the ionic lattice. All ionic compounds form lattices and crystals when solid. Why do ionic compounds form crystals?
7 of 13© Boardworks Ltd 2012 Heating ionic compounds Why are ionic compounds solid at room temperature and have high melting points and boiling points? Larger ionic charges produce stronger ionic bonds and so much more heat is required to break the ionic bonds in magnesium oxide than in sodium chloride. sodium chloride magnesium oxide compound ion charges melting point ( o C) boiling point ( o C) 1 + and and ,413 2,8523,600 strong ionic bonds hold ions together Ionic bonds are strong and a lot of heat is needed to break them.

9 of 13© Boardworks Ltd 2012 Electrical conductivity
10 of 13© Boardworks Ltd 2012 When liquid (molten), the ions can break free of the lattice and are able to move. The ions are charged particles and so can carry an electric current. As solids, ionic compounds cannot conduct electricity because their ions are bonded together in the lattice. ions in solid state cannot move ions in molten state can move and conduct electricity Ionic compounds are usually soluble in water because water molecules have a slight electrical charge and so can attract the ions away from the lattice. When dissolved, the ions are free to move and can carry an electric current. How can ionic compounds conduct electricity?
