Explanation:
Calcium fluoride (CaF2) crystallizes in the fluorite structure, which is a face-centered cubic (FCC) lattice.
The fluorite structure consists of a close-packed arrangement of fluoride ions (anions) and calcium ions (cations) occupying the octahedral holes between the fluoride ions.
Coordination Number of the Cation:
The coordination number of a cation refers to the number of anions that surround it in the crystal lattice.
In the fluorite structure, each calcium ion (Ca2+) is surrounded by 8 fluoride ions (F-) in a cubic arrangement. This is because each calcium ion is located at the center of a cube, and each corner of the cube is occupied by a fluoride ion. Therefore, the coordination number of the cation (Ca2+) in calcium fluoride is 8.
Coordination Number of the Anion:
The coordination number of an anion refers to the number of cations that surround it in the crystal lattice.
In the fluorite structure, each fluoride ion (F-) is surrounded by 4 calcium ions (Ca2+) in a tetrahedral arrangement. This is because each fluoride ion is located at the center of a tetrahedron, and each vertex of the tetrahedron is occupied by a calcium ion. Therefore, the coordination number of the anion (F-) in calcium fluoride is 4.
Conclusion:
Therefore, the coordination number for the cation (Ca2+) in calcium fluoride is 8, and the coordination number for the anion (F-) is 4. The correct answer is option D.

- Calcium fluoride (CaF\(_2\)) crystallizes in the fluorite structure.
- In this structure:
- Calcium ions (Ca\(^{2+}\)) are at the center of a cube surrounded by 8 fluoride ions (F\(^-\)). Thus, the coordination number for Ca\(^{2+}\) is 8.
- Fluoride ions (F\(^-\)) are surrounded by 4 calcium ions (Ca\(^{2+}\)). Thus, the coordination number for F\(^-\) is 4.
- Therefore, the coordination numbers for the cation and anion are 8 and 4, respectively. This corresponds to option D: 8, 4.
