KCl crystallizes in a cubic unit cell with Cl^- ions on each corner and each face.How many K⁺ ions and Cl^- ions are in each unit cell of KCl? A)1 K⁺ ion and 1 Cl^- ion B)2 K⁺ ions and 2 Cl^- ions C)4 K⁺ ions and 4 Cl^- ions D)8 K⁺ ions and 8 Cl^- ions

Question

Quizplus · Accepted Answer

In a face-centered cubic (FCC) structure, Cl⁻ ions are at the corners and faces, contributing 4 Cl⁻ ions per unit cell. K⁺ ions occupy the octahedral holes, also contributing 4 K⁺ ions per unit cell.
