This video is based on the AQA spec. If you are following a different exam board then you should check your specification.

In this video, we look at elements, compounds, mixtures and molecules. First we look at the idea of an element, using examples from the periodic table. I then show you the definition of a compound and the definition of a mixture and how compounds are different from mixtures. Finally, we look at molecules and see how these can be elements or compounds.
