Lesson details
Key learning points
- Salts form ionic structures because they contain metal and non-metal ions.
- In an ionic structure each positive ion attracts the negative ions and vice-versa.
- Metal ions attract all non-metal ions and vice-versa, they bond to the opposite charged ions that are closest.
- An ionic bond is the electrostatic force of attraction between oppositely-charged ions acting in all directions.
- Ionic substances are 3D lattices with regular arrangements of ions ( in a repeating pattern of +ve and -ve charge).
Keywords
Ionic bond - the electrostatic force of attraction between oppositely-charged ions acting in all directions
Ball-and-stick model - used to represent the atoms and bonds in a chemical compound
Lattice - the regular arrangement of atoms or ions in a 3D space
Common misconception
That the ionic bond is the transfer of electrons and not the electrostatic forces of attraction between the ions. The ball and stick model implies that there is a physical link between the ions.
Ensure that students have a good understanding of how ions are formed and that ionic bond forms when oppostive ions attract; before moving on to dot and cross diagrams for binary ionic substances.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
