Determine the number of atoms per unit cell in a body-centered cubic $(BCC)$ unit cell.

An ionic solid $AB$ crystallizes in a $NaCl$-type structure,where $A$ ions are at the corners of the cube. If all face-centered ions along one axis are removed,then the stoichiometry of the resulting solid will be .....

The crystal structure of the solid compound $XY$ is similar to $NaCl$. If the radius of the cation $X^+$ is $100 \, pm$, then the radius of the anion $Y^-$ will be ......... $pm$.

In metallic solids,the number of atoms for the face-centered and the body-centered cubic unit cells are,respectively:

What is the number of atoms per unit cell in a body-centered cubic $(BCC)$ unit cell?

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