In the sodium chloride unit cell the chloride ions form a cu

In the sodium chloride unit cell, the chloride ions form a cube in which each side is arranged like the following figure. The circles represent the positions of the chloride ions on one square face of the cube. All the other faces are the same. What is the name of this unit cell? O-O a. body-centered cubic b.x-face cubic c. face-centered cubic d. simple cubic e. chloride-centered cubic

Solution

THE given square face represents the face centred cubic system (c) in which atoms are present at the corner of the cubic , and one atom is present at each face of the cube , so FCC type lattice
