Chemistry Unit 1 - Atomic structure and the periodic table

Students have already met in year 7 and 8 the idea everything in the universe is made up of particles.  Students will have looked at the Periodic table and should know about metals, non-metals and their properties.  Student will have worked on developing their practical skills and investigated how to separate out mixtures

This unit will help them to develop their ideas further - they will look at the different models that we can use to represent an atom and how this has changed over the centuries as scientists have carried out more and more experiments.  Students will look at how the electron structure of an atom can give us information on the reactivity and the patterns of reactivity that are present in the periodic table.

We will also learn how we can use radioactive iostopes to date old objects.
