CHEM1101 - This Week's Resources

Topics and Learning Outcomes

  • The Periodic Table and Periodic Trends
    •  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
  • Bonding - MO theory
    •  explain how electron sharing leads to lowering of electronic energy in terms of increasing the de Broglie wavelength.
    •  predict electronic configurations and bond orders for diatomic molecules, given a molecular orbital (MO) energy diagram
    •  predict relative binding energies and bond lengths from bond order
    •  recognise a bonding or antibonding orbital from the lobe representation
    •  recognize a σ orbital and a σ* orbital
    •  recognize a π orbital, a π orbital and a non-bonding orbital
    •  identify the valence electrons and orbitals in diatomic molecules
    •  distinguish between polar and apolar bonds in diatomic molecules and relate it to electron attraction of a nucleus (electronegativity)
    •  draw out ground state electronic configurations for molecules and molecular ions given their allowed energy levels
    •  calculate bond order from molecular electronic configurations
    •  explain the difference between paramagnetism and diamagnetism
    •  predict whether a molecule will be diamagnetic or paramagnetic from its orbital energy diagram
    •  recall the meaning of HOMO and LUMO and determine the lowest energy electronic transition
