KF crystallizes in a face-centered cubic cell.What is the total number of ions (K⁺ ions and F^- ions)that lie within a unit cell of KF? A)2 B)8 C)6 D)5 E)4

Question

Quizplus · Accepted Answer

In a face-centered cubic cell, there are 4 ions located at the corners and 4 ions located at the center of the faces. For KF, the unit cell contains one K+ ion and one F- ion. Thus, there are a total of 8 ions (4 K+ and 4 F-) within a unit cell of KF.
