Explanation:
The correct statement among the given options is option B: The coordination number of the fluoride ion in the fluorite type structure is 4.
Fluorite type structure:
- The fluorite type structure is a common arrangement found in many ionic compounds, such as calcium fluoride (CaF2).
- In this structure, the cations occupy the face-centered cubic (FCC) lattice positions, while the anions occupy the tetrahedral holes within the lattice.
- Each cation is surrounded by 8 anions and each anion is surrounded by 4 cations.
Coordination number:
- The coordination number is the number of ions or atoms that surround a central ion or atom in a crystal lattice structure.
- In the case of the fluorite type structure, the coordination number of the fluoride ion is 4 because each fluoride ion is surrounded by 4 calcium ions in a tetrahedral arrangement.
Other options:
a) The number of formula units of CsCl per unit cell in a CsCl structure is 1, not 4. In the CsCl structure, each unit cell contains one Cs+ ion and one Cl- ion.
c) The number of formula units of NaCl per unit cell in a rock salt structure is 4, not 1. In the rock salt structure, each unit cell contains 4 Na+ ions and 4 Cl- ions.
d) The coordination number of the chloride ion in the rock salt type structure is 6, not 2. In the rock salt structure, each chloride ion is surrounded by 6 sodium ions in an octahedral arrangement.
Therefore, the correct statement is option B: The coordination number of the fluoride ion in the fluorite type structure is 4.

In fluorite structure, Ca2+ forms CCP while F- anions occupy all the tetrahedral voids hence coordination number of F- is 4.
