To succeed in this topic, you need to:

  • Be familiar with the different types and shapes of atomic orbitals.
  • Be able to describe how atomic orbitals overlap to form sigma- and pi- covalent bonds.
  • Be familiar with electron configuration in terms of the energy levels occupied by electrons in atomic orbitals.

After working through this Chemistry Factsheet, you will:

  • Be able to describe molecular orbital theory as the overlap of atomic orbitals.
  • Be able to describe the wave properties of electrons on creating bonding molecular orbitals and anti-bonding molecular orbitals.
  • Be able to show energy level diagrams for the formation of example molecules, including the hydrogen molecule and oxygen molecule.
