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.
Chemistry for the gifted and talented is a refreshingly challenging educational book containing a wide range of differentiated activities for use in school and college.
