How do I write the electron configuration of an oxygen molecule?

Solution

Aufbau Principle

  • Aufabu principle determines the shell, subshell, and orbital in which the incoming electrons are to be filled according to their energy levels.
  • The preference for the filling up of electrons according to their energy levels is: 1s,2s,2p,3s,3p,4s,3d,4p,5s,4d,5p,6s,4f,5d,6p,7s,5f,6d,7p,8s
  • However, molecular orbital theory describes the electronic configuration of molecular species such as oxygen molecule.
  • The electronic configuration for a molecule containing 16 or more than 16 electrons according to MOT is given by:
  • σ1s,σ*1s,σ2s,σ*2s,σ2pz,π2px=π2py,π*2px=π*2py,σ*2pz

Electronic configuration of oxygen molecule:

  • Oxygen molecule has 16 electrons, so the electronic configuration of oxygen molecule becomes:
  • σ1s2,σ*1s2,σ2s2,σ*2s2,σ2pz2,π2px2=π2py2,π*2px1=π*2py1,
