The number of octahedral voids per lattice site in a lattice is $...$ (Rounded off to the nearest integer).

What is the coordination number of any particle in the $fcc$ (face-centered cubic) crystal lattice?

If the radius ratio is in the range of $0.732 - 1.000$,then the coordination number will be

In a mixed oxide of two metals $X$ and $Y$,divalent $X^{2+}$ ions occupy $50\%$ of the tetrahedral voids,while trivalent $Y^{3+}$ ions occupy $50\%$ of the octahedral voids. The formula of the oxide is:

An element crystallizes in a structure such that the unit cell is a cube with one atom at each corner and two atoms on its body diagonal. If the volume of this unit cell is $24 \times 10^{-24} \, cm^3$ and the density of the element is $7.2 \, g \, cm^{-3}$,calculate the number of atoms present in $200 \, g$ of the element.

The structure of $TlCl$ is similar to $CsCl$. What would be the radius ratio in $TlCl$?
