Lesson details
Key learning points
- Metals are good electrical conductors and good thermal conductors.
- Metals can be stretched into wires, or bent/hammered into different shapes.
- Individual atoms do not have the physical properties of the substances that contain them.
- Metallic structures consist of positive ions and free–moving outer shell electrons.
- Electrostatic forces of attraction between ions and free electrons bind them all together in a giant metallic structure.
Keywords
Malleable - A malleable substance can be hammered or pressed into shape without breaking.
Ductile - A ductile substance has the ability to be drawn into a wire.
Delocalised - Electrons are said to be delocalised when they are free to move through the structure of a metal and can carry an electrical current.
Conductor - A conductor is a substance that allows charge or energy to flow through it easily due to the presence of delocalised electrons.
Forces of attraction - A force of attraction refers to the strength of the pull between two objects either due to their mass, their charge or the presence of magnetic poles.
Common misconception
A metal is an individual atom. The property of a metal atom is the same as the bulk material. Pupils get confused between the attractive forces in the metal atoms and the metallic bond.
Reinforce the idea that atoms are tiny and not visible to the naked eye. The material we know as metal is many millions of atoms joined together. Revisit the structure of the atoms before introducing the idea of metallic bonding and giant structure.

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.
