Lesson details
Key learning points
- There are three different types of bonding (covalent, ionic, metallic).
- There are only two types of structure (simple and giant).
- The type of bonding and structure are what lead to properties of substances.
- Melting/boiling points are linked to intermolecular forces (simple) and bond strength (giant).
- Conductivity is linked to whether there are free moving charge carriers.
Keywords
Bonding - Refers to the force of attraction between atoms or ions that hold them together.
Force of attraction - Refers to any force that causes two or more substances to come together.
Structure - Structures in chemistry are determined by the type of bonding and arrangement of atoms or ions.
Property - A feature or characteristic of a substance that can be used to classify it, or describe how it behaves.
Charge carrier - Particles that enable electrical conductivity, such as delocalised electrons or free–moving ions.
Common misconception
Ionic substances are binary compounds. Bonding and structure are the same thing. Only bonding influences properties.
As well as multiple ions in ionic substances, there can be polyatomic ions too. Bonding informs structure, and bonding and structure together influences properties.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
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.

6 Questions
Q1.Why do atoms form bonds?
Q2.Match the type of bonding to its description:
Electrons are shared between atoms.
Electrons are transferred, so charged ions, not atoms, are bonded.
Electrons are delocalised among a lattice of metal ions.
Q3.What type of bonding can be found between non–metal atoms?
Q4.From the diagrams below, select the image depicting a substance with ionic bonding.
Q5.What is a key characteristic of metallic bonding?
Q6.Which of the following substances would you expect to conduct electricity when solid?
