Current Question (ID: 17906)

Question:

$\text{The correct statement(s) among the above is -}$ $\text{a. The coordination number of a cation occupying a tetrahedral hole is 4.}$ $\text{b. The coordination number of a cation occupying an octahedral hole is 6.}$ $\text{c. In Schottky defect, the density of the lattice decreases.}$

Options:

1. $\text{a, b}$
2. $\text{b, c}$
3. $\text{a, b, c}$
4. $\text{a, c}$

Solution:

$\text{HINT: In the Schottky defect, an equal number of cation and anion are missing from the crystal lattice.}$ $\text{Explanation:}$ $\text{Since tetrahedral holes are surrounded by 4 nearest neighbors. So, the coordination number of a cation occupying a tetrahedral hole is 4.}$ $\text{Since the octahedral hole is surrounded by six nearest neighbors. So, the coordination number of a cation occupying octahedral is 6.}$ $\text{In the Schottky defect, a pair of anion and cation leaves the lattice. So, the density of lattice decreases.}$
