Question

where is the negative ion of fluorite lattice located?​

Answer 1

Answer:

THE ANSWER TO THE QUESTION IS THAT THE FLUORIDE  IONS ARE LOCATED AT THE TETRAHEDRAL VOIDS OF THE FLUORITE LATTICE

Explanation:

The formula for fluorite lattice is CaF2

POSITIVE ION:CALCIUM ION

NEGATIVE ION:FLUORIDE ION

The calcium ions form a ccp lattice i.e a cubic closed packing lattice wherein they are located at the corners of the cube and centre of each face of the cube .

The fluoride ions are present in the tetrahedral voids of the ccp lattice

The coordination number of the fluoride ions is 4 as the species present in the tetrahedral voids of a ccp lattice are surrounded by 4 other nearest neighbor.

Other such compounds which exhibit the similar structures include the fluorides of the alkaline earth metals such as barium i.e BaF2.

This structure is popularly called the fluorite structure.

In the image attached below the calcium ions are indicated by green spheres and the fluoride ions are indicated by blue spheres.

Answer 2

The negative ion of fluorite lattice is located in tetrahedral voids.

Explanation:  

• The molecular formula of fluorite is $CaF _{2}$. Theatre positive charge that is present in calcium and the negative charge that is present is fluorine.  

• In the lattice structure calcium is located at the edges of the cube and at the centre of each face of the cube.  

• This type of lattice formation is known as a closed cubic packing.  

• Fluorine ions are present at the tetrahedral void of the cubic structure. The negative charges are also located at these points.
