1. Revision for test
Year 9 C2

2. What you need to revise – the basics
Pages 22-23: C2.1 DEVELOPMENT OF THE PERIODIC TABLE
What are the main theories and who came up with them? Make sure you know Mendeleev’s theory well.
Pages 24-25: C2.2 ELECTRONIC STRUCTURES AND PERIODIC TABLE
In what order are the elements arranged and how is electronic structure linked to properties?
Pages 26-27: C2.3 GROUP 1 THE ALKALI METALS
What is their structure and what are their common properties – link these.
Pages 28-29: C2.4 GROUP 7 THE HALOGENS
What is their structure and what are their common properties – link these. Make sure you know their colours!
Pages 30-31: C2.5 EXPLAINING TRENDS
What does electrostatic attraction depend on and how does this affect reactivity.
NB – you will also need to recall the reactivity of the noble gases
Separate Science Only:
Pages 32-33: C2.6 THE TRANSITION ELEMENTS 
Add to your poster by going through your class notes and making more notes and add diagrams and pictures and highlighting any keywords!
