Factors Affecting Lattice Enthalpy
Investigating the impact of ionic charge and size on the magnitude of lattice enthalpy.
Key Questions
- Compare the lattice enthalpies of compounds with different ionic charges but similar sizes.
- Predict how increasing the ionic radius would affect the lattice enthalpy of an ionic compound.
- Justify why magnesium oxide has a significantly higher lattice enthalpy than sodium chloride.
