If the pressure on a $NaCl$ structure is increased,then its coordination number will

What is the coordination number of $Cu$ in a face-centered cubic $(fcc)$ lattice?

Which of the following is correct for the crystal lattices mentioned below?

The number of atoms in body-centred and face-centred cubic unit cells are, respectively:

Predict the close-packed structure of an ionic compound $A^{+} B^{-}$ in which the radius of cation and anion are $148 \ pm$ and $195 \ pm$ respectively.

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.
