Exploring: The properties of oxides Students look for a in the pH of oxides of elements going across the periodic table by testing the type of solution/pH of oxides of different elements in water. Explaining: Different structures Show students the structure of different oxides representing molecular and lattice structures using molecular models, e.g. sulfur dioxide molecules and a magnesium oxide lattice.
