Question

Select the correct statement(s);
The C.N. of cation occupying a
tetrahedral hole is 4.
The C.N. of cation occupying a
octahedral hole is 6.
In schottky defects, density of the
lattice decreases.
The C.N. of cation occupying a
octahedral hole is 8.​

Answer 1

Explanation:

Since terthadral holes are surrounded by a nearest neighours so, the

of cation occupying tetrahedral hole is

since octahedral holes is surrounded by six nearest neighource so,

of cation accopying outahedral is

In schotily defecty defects a parts of anion and cation so density of lattice decreases
