Final answer:
Yes, lithium fluoride (LiF) has a face-centered cubic (FCC) crystal structure.
Step-by-step explanation:
Yes, lithium fluoride (LiF) has a face-centered cubic (FCC) crystal structure.
In an FCC unit cell of LiF, the lithium ions (Li+) are located at the lattice points, which form a simple cubic array. The fluoride ions (F-) occupy all of the tetrahedral sites between the lithium ions.
This structure gives a lithium:fluorine ratio of 1:1, as required by the chemical formula LiF.
