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

• draw out the electron configuration for atoms in the s-and p-blocks of the Periodic Table, including unpaired electrons
• explain why the orbitals with the same principal quantum number but different angular momentum quantum numbers have different energies in multi-electron atoms
• explain periodic trends in atomic radii and ionization energies in terms of quantum theory
• define electron affinity and explain some features of its periodic trends in terms of electronic configurations derived from quantum theory.

• Sections 4.5 and 4.6 (in Blackman, Bottle, Schmid, Mocerino and Wille, Chemistry, 3^rd Edition, 2015 (John Wiley))

• Electronic configurations (in ChemWiki)
