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

Calculate the number of atoms per unit cell in a face-centered cubic $(fcc)$ unit cell.

$A$ solid compound contains atoms $X, Y,$ and $Z$. In its unit cell,atoms $X$ are at the corners,atoms $Y$ are at the body center,and atoms $Z$ are at the face centers. The formula of the compound is:

The $FCC$ crystal contains how many atoms in each unit cell?

In the crystal of $CsCl$,the nearest neighbours of each $Cs^+$ ion are

In $CsCl$ structure,the coordination number of $Cs^{+}$ is
