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

• represent a dipole in a bond, and use electronegativity to identify the positive and negative ends
• describe and explain the periodic trends in electronegativity

• Sections 5.5 and 6.8 (in Blackman, Bottle, Schmid, Mocerino and Wille, Chemistry, 3^rd Edition, 2015 (John Wiley))

• Lewis theory of bonding (in ChemWiki)
