In the zinc blende structure,zinc atoms fill up:

The face diagonal length of $f.c.c.$ cubic cell is $660 \sqrt{2} \, pm$. If the radius of the cation is $110 \, pm$,the radius of the anion is ............ $pm$.

What is the coordination number of $Zn$ in the crystal structure of $Zn$?

Argon crystallizes in such a way that the positions of the atoms are at $(0, 0, 0)$,$(0, 1/2, 1/2)$,$(1/2, 0, 1/2)$,and $(1/2, 1/2, 0)$. The type of unit cell is:

$Zn$ transforms from its solid state to its molten state. What is its coordination number in the molten state?

How many atoms are there in a cube-based unit cell,having one atom on each corner and $2$ atoms on each body diagonal of the cube?
