Question

The 8 : 8 type of packing is present in___________?($Mg{F}_2$ $,CsCl$)

Answer 1

In Cesium chloride crystal lattice (CsCl), Each $C{s}^{+}$ is surrounded by 8 $C{l}^{–}$ at the corners of each cube.

So, the $C{s}^{+}$ coordination number is 8.

Each $C{l}^{–}$ is also surrounded by 8 $C{s}^{+}$ at the corners of a cube.

So, the $C{l}^{–}$ has coordination number equals to 8.
