Description
At the end of this activity, students should be able to: – describe the formation of an ionic compound as a series of steps – explain every step in the formation of an ionic compound and the enthalpy changes involved: enthalpy of atomisation, ionisation enthalpy, electron affinity and lattice formation enthalpy – describe a Born–Haber cycle as an energy diagram linking the enthalpy of formation to the enthalpy changes of atomisation, ionisation and crystal lattice formation – use a Born–Haber cycle to calculate enthalpy changes and to predict the stability of an ionic compound.
