Ionic bonding teaching resources

Worksheets and lesson ideas to challenge students aged 11 to 16 to think hard about ions and ionic bonding (GCSE and Key Stage 3)

Where to begin when teaching ionic bonding? Do you start with the reaction of sodium with chlorine? Or do you start with the ionic lattice and then move to the electronic configuration of the ions? Whatever your route, make sure you start with something that makes sense to students i.e. it’s something they can see, taste or touch. Whether it’s salty chips or explosive reactions make the abstract accessible.

Atom or ion?

atom or ionGCSE worksheet that asks students to decide if a model shows an atom or an ion. This is an excellent activity to probe students’ understanding of charge, atoms and ions. Students are presented with a range of different models. They decide if the overall charge is neutral i.e. the model represents an atom, or if the overall charge is positive or negative i.e. the model represents an ion.

Ionic dot and cross diagrams

GCSE worksheet for drawing dot and cross diagrams for ionic bonding. Students follow a modelled method to draw dot and cross diagrams for a range of simple ionic compounds. (PDF)

Properties of ionic substances – building ionic lattices

GCSE worksheet on explaining properties of ionic substances. Students build a model of an ionic lattice using plasticine and straws. They then use this model to explain a variety of physical properties of sodium chloride including high melting point, conductivity and brittleness. (PDF)
