What is the coordination number of $Zn^{2+}$ and $S^{2-}$ ions in the zinc blende $(ZnS)$ structure?

When a $CsCl$ type crystal is heated to a very high temperature,the coordination number of the cation becomes .....

What is the coordination number of a particle in an $fcc$ crystal lattice?

In a solid $AB$,$A$ atoms are in $ccp$ arrangement and $B$ atoms occupy all the octahedral sites. If two atoms from the opposite faces are removed,then the resultant stoichiometry of the compound is $A_{x} B_{y}$. The value of $x$ is ..... [nearest integer]

Explain the calculation of the number of atoms in a primitive cubic unit cell.
