Which of the following crystal defects are generally shown by nonionic solids?

Options

A. Vacancy defects
B. interstitial defects
C. Stoichiometric defects
D. Both (1) and (2)

Answer

4

Explanation

Noninal crystals is said to have vacancy defect when some of the lattice sites are vacant in the crystalline substance. This generally arises due to absorption of heat form the surrounding. That is why it is called a thermodynamic defect or intrinsic defect.
the nonionic crystal is said to have intrisnisic defeat when some constituent particles are present in the interstitial sites. It is another example of intrisnisic defect. Both these defects are examples of stoichiometric defeat a sstoichiometry of the solid is not disturbed by these defects.
