An ionic crystal $LiAg$ arranges in a cubic crystal system in which the coordination number of each $Li^+$ and $Ag^+$ is $8$. The crystal structure is:

The number of $Cl^{-}$ ions around one $Na^{+}$ in $NaCl$ crystal lattice is

The number of carbon atoms per unit cell of diamond unit cell is

In a face centered cubic lattice,atoms $A$ are at the corner points and atoms $B$ are at the face centered points. If one atom $B$ is missing from one of the face centered points,the formula of the ionic compound is:

Copper crystallizes in $f.c.c.$ with a unit cell length of $361 \ pm$. What is the radius of copper atom? (in $pm$)

What is the total number of ions present in one unit cell of sodium chloride lattice?
