Learning outcomes - after studying this topic, you should be able to:

• explain the shape of the Periodic Table using the quantum chemical atomic model
• recognise trends in the Periodic Table, such as atomic radii, ionic radii and ionisation energies
• understand and explain reasons for these trends
• use trends to predict reactivity

• Sections 4.8 and 4.9 (in Blackman, Bottle, Schmid, Mocerino and Wille, Chemistry, 3^rd Edition, 2015 (John Wiley) )

• Periodic trends (in ChemWiki)
