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

• give examples of periodic trends and chemical properties used to construct the Periodic Table.
• assign atoms to appropriate groups in the Periodic Table on the basis of their properties
• explain the historic significance of key events in the development of modern atomic structure theory, such as nuclear charge, atomic mass and the discovery of the neutron
• define ionization energy and atomic radius and know their trends in the Periodic Table.

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

• Periodic trends (in ChemWiki)
