ResourceShapes of molecules and ions
This activity draws some extra concepts and mathematical skills into the discussion of molecular shape. A distinction between geometry around the central atom and the shape of the molecule is made.
-
ResourceOxidation numbers
This activity introduces oxidation numbers by giving a conceptual foundation for them in terms of electron accounting and polar bonds. It then shows how the model used so far needs refining.
-
ResourceFormal charge
This activity introduces formal charge – a useful tool which otherwise might not be taught. The formal charge model treats bonds as pure covalent, in contrast to the oxidation state model which treats bonds as ionic.
-
ResourceCovalent bonding
This activity seeks to develop an understanding of covalent bonding in terms of energetic stability rather than full shells.
