Question

The 8 : 8 type of packing is present in:

• A. $Mg{F}_2$
• B. $CsCl$
• C. $KCl$
• D. $None$

Answer 1

The correct option is B $CsCl$

solution:

Co-ordination number can be described as the number of atom or ions which are immediately next to a central atom or ion in a crystalline structure.

The 8:8 type of packing is present in option CsCl (Caesium Chloride).

This is because it has a co-ordination number of 8. Therefore, its lattice also has a 8:8 structure.

hence option B is correct
