Metal oxides and non-metal oxides
Lesson details
Learning outcome
I can describe the properties of metal and non-metal oxides and write equations to represent reactions of metal oxides with acid.
Key learning points
- A metal oxide consists of metal atoms bonded to oxygen atoms.
- Metal oxides are bases and can react with acids to neutralise them.
- Metal oxide + acid ⭢ metal salt + water
- A non-metal oxide consists of non-metal atoms bonded to oxygen atoms.
- Non-metal oxides in water make acidic solutions.
Keywords
Metal oxide - consists of metal atoms bonded to oxygen atoms.
Adding to excess - when a reactant is present in a greater amount than is necessary to completely react.
Non-metal oxide - consists of non-metal atoms bonded to oxygen atoms.
Common misconception
Pupils find it difficult to carry out a complex 3-stage practical.
Demonstrate the practical or do a 'follow with me' step-by-step method. If you are short on time you could just carry out the first part of the practical to produce the copper sulfate solution then stop.
Teacher tip
Non-metal oxides placed in water cause a reaction. To avoid teaching another reaction at this stage, refer to, and label, the solutions as non-metal oxides in water and use dilute solutions of HNO₃, H₂SO₄ and H₃PO₄. The acidity of the oxides could be linked to environmental issues such as acid rain.
Equipment
Heat resistant mat, Bunsen burner, gauze, tripod, beaker, spatula, stirring rod, conical flask, filter paper, funnel, evaporating basin, copper oxide, sulfuric acid.

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.
