Question

Quizplus · Accepted Answer

The ClF1F1F1S1^F1F1F10 ion has a face-centered cubic structure, where the Cl ion is at the center of the cube and the eight F1F1F1S1 ions are located at the eight corners of the cube. In addition, there are six face-centered F1F1F1S1 ions located in each face of the cube. Therefore, the best choice is B, which accounts for 1/8 of the eight corner atoms and 1/2 of the six face atoms in the unit cell.
