One hour lesson on the Halogens covering the following objectives:
To be able to describe the properties of the Halogens
To be able to explain the displacement reaction to show the order of reactivity of the halogens

There is one worksheet missing which is from the 2011 Edexcel pearson resources pack but can easily be substituted with any other worksheet on the Halogen properties.
