Lithium chloride crystallizes in a face-centered cubic structure.The unit cell length is 5.14 × 10^-8 cm.The chloride ions are touching each other along the face diagonal of the unit cell.The lithium ions fit into the holes between the chloride ions.How many chloride ions are there in this unit cell? A)4 B)3 C)1 D)8 E)2

Question

Quizplus · Accepted Answer

In a face-centered cubic (FCC) structure, there are 4 formula units per unit cell. Since each formula unit of lithium chloride (LiCl) contains one chloride ion, there are 4 chloride ions in the unit cell.
