Explain how sodium chloride and caesium chloride are different in terms of arrangement of the particles.
- In order to maximise electrostatic attraction and to minimise repulsion
- oppositely charged ions pack around each other
- which increase the bond energy
- 8 chloride anions can fit around the larger caesium ions
- While the smaller sodium ions can only fit around 6
- CsCl is an 8:8 ratio
- NaCl is a 6:6 ratio
