The number of hexagonal faces that are present in a truncated octahedron is

If the radius ratio limit is $0.414 - 0.732$,what will be the coordination number?

The $FCC$ unit cell of a compound contains ions of $A$ at the corners and ions of $B$ at the centre of each face. What is the formula of the compound?

What is the volume occupied by particles in $BCC$ structure if '$a$' is the edge length of the unit cell?

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.

In an end-centered unit cell,the body diagonal contains two additional atoms. What is the total number of atoms present in the unit cell?
