BaCl₂ crystallizes such that the Ba²⁺ ions are in a face-centered cubic arrangement and the Cl^- ions are in the holes of the lattice (fluorite structure). How many Cl^- ions are present in one unit cell of this crystal A) 1 B) 2 C) 4 D) 6 E) 8

Question

Quizplus · Accepted Answer

In a fluorite structure, the anions (in this case, Cl-) occupy all the tetrahedral holes of the face-centered cubic lattice formed by the cations (Ba2+). In a face-centered cubic (FCC) lattice, there are 8 tetrahedral holes, so there are 8 Cl- ions in one unit cell.
