Perfect Ionic Model Flashcards
1
Q
What does the perfect ionic model assume
A
Ions are perfect spheres held together only by electrostatic attraction
2
Q
What is the perfect ionic model used for
A
Theoretical calculations of lattice enthalpies
3
Q
How might theoretical and actual lattice enthalpies differ
A
Covalent character causes true value to be larger than the theoretical
4
Q
How is true value of lattice enthalpy calculated
A
Born haber cycle
