3 x 1 hour lessons

This module explores periodic trends and group chemistry, focusing on Period 3 elements and Group 2 metals. You’ll study trends in atomic structure, reactivity, and properties, as well as uses of Group 2 compounds and chlorine in industrial and domestic contexts.

​

By the end of this module you will be able to:

• describe and explain trends across Period 3 and down Group 2

• predict and explain reactions of Group 2 metals and their compounds

• explain and recall reactions of Period 3 elements and their oxides

• evaluate the uses of chlorine and chlorate(I) in water treatment and other applications

• interpret the classification and structure of the Periodic Table
