ResourceJournal articles made easy: Predict crystallinity
This article looks at predicting and controlling the crystallinity of molecular materials. It will help you understand the research the journal article is based on, and how to read and understand journal articles. The research article was originally published in our CrystEngComm journal. Will it crystallise?Predicting crystallinity of molecular materialsClick ...

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.
-
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.
