ResourceCovalent bonding
This activity seeks to develop an understanding of covalent bonding in terms of energetic stability rather than full shells.
-
ResourceIonic bonding
An explanation often given for ionic bonding is that atoms lose or gain electrons to achieve noble gas configurations. This activity evaluates that as a complete explanation.
-
ResourceBonding models
This activity gets the students to think of the model they have been taught as a model rather than the truth.
-
ResourceAtoms, elements, molecules, compounds and mixtures
This activity is designed to help students clarify the relationship between atoms, elements, molecules, compounds and mixtures. It also develops the skill of using Venn diagrams in organising their understanding.

ResourceThe atom detectives
This resource presents chemists as real people and not stereotypical ‘mad scientists’ whose lives are completely dominated by science.
