Topics and Learning Outcomes

The Periodic Table and Periodic Trends
- 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.

Bonding in H₂ - MO theory
- explain the reason for bond formation being due to energy lowering of delocalised electrons in molecular orbitals
- describe a molecular orbital
- recognise sigma bonding, sigma* antibonding and non-bonding orbitals
- assign the (ground) electron configuration of a diatomic molecule.
- define HOMO and LUMO, and homonuclear and heteronuclear diatomic molecules

Bonding in O₂, N₂, C₂H₂ and C₂H₄
- distinguish between various types of bonding, anti-bonding and non-bonding orbitals
- distinguish between polar and apolar bonds in diatomic molecules and relate it to electron attraction of a nucleus
- draw out ground state electronic configurations for molecules and molecular ions given their allowed energy levels
- calculate bond order from molecular electronic configurations
- relate Electronic Absorbance Spectra to electronic structure
