*** WHAT'S COVERED ***
1. The structure of ionic compounds
* How ionic bonds form through electron transfer between metals and non-metals.
* The formation of giant ionic lattice structures due to strong electrostatic forces.
* Different ways to represent ionic compounds, including dot-and-cross and ball-and-stick diagrams.
2. The properties of ionic compounds
* Why they have high melting and boiling points, related to the energy needed to break strong ionic bonds.
* Electrical conductivity explained: they conduct when molten or dissolved because ions are free to move, but not when solid as ions are in fixed positions.
3. How to determine the chemical formula of an ionic compound
* The principle of balancing the charges of positive and negative ions to create a neutral compound.
* Working out the formula for simple compounds like sodium chloride and magnesium chloride.
* How to deduce the formula for compounds containing polyatomic ions, such as calcium hydroxide and aluminium sulphate.
* A list of common polyatomic ions to memorise, including hydroxide, sulphate, nitrate, carbonate, and ammonium.
