Final answer:
Lithium fluoride (LiF) is not face-centered cubic (fcc) but instead crystallizes in a body-centered cubic (bcc) structure.
Step-by-step explanation:
Lithium fluoride (LiF) is not face-centered cubic (fcc). Instead, lithium fluoride crystallizes in a body-centered cubic (bcc) structure.
In a bcc structure, metal atoms occupy the eight corners of a cube along with one atom in the very center. The coordination number of each atom in the bcc structure is 8.
