Born Haber Level DiagramBorn-Haber cycle energy level diagram for iron(III) oxide Fe2O3 showing atomisation, ionisation energies, electron affinities, lattice enthalpy and enthalpy of formation

Always start your cycle at datum line, i.e. at zero enthalpy. Tip: You may combine the ionisation energies for Fe or for other metals.
Multiple electron affinities can also be combined.

Take note that for energy level diagram, you will have to show the ionized electrons from Fe. When you use bond energy instead of enthalpy of atomisation, you will need to multiply by the correct coefficient. Lastly, don’t forget to put your state symbols! 🙂

Hope this has been useful for you, if you wish to learn how to draw the diagram using energy cycle, go here.
