What is the difference between crystals formed by sodium chloride and those formed by cesium chloride?

Question

What similarities and differences am I supposed to look for?

Answer 1

Sodium chloride is Face centered cubic lattice whereas Cesium chloride is body centered cubic lattice.

In FCC, there are 27 lattice points and therefore ratio of the ions is 4:4 that means one Unit cell of FCC structure contains 4 ion pairs whereas in BCC, there are only 9 lattice points that means the ratio of the ions is 1:1 and hence it contains only one ion- pair in BCC structure.
