Question

How are the coordinate numner of Ca2+ and F- ions in CaF2 related?​

Answer 1

Answer:

The Ca 2+ and F−are located in CaF 2crystal respectively at face-centred cubic lattice points and in tetrahedral voids. The calcium fluoride structure is also called fluorite structure. It is 8:4 arrangement, the coordination number of Ca2+and F−ions is 8 and 4 ions respectively.

Answer 2

Answer:

✌✨✡_ I HOPE HELP YOU _✡✨✌

Explanation:

• In CaF2 the coordination number of Ca2+ is 8. As it is surrounded by 8 F ions. In CaF2 the coordination number of F- is 4. As it is surrounded by 4 Ca ions...
