Question

write about the Nonstoichiometric defects​

Answer 1

Answer:

Nonstoichiometric defect arises when the ratio of number of atoms of one kind to that of other kind or the ratio of number of cations to anions becomes different from that indicated by its chemical formula. In short, stoichiometry of the compound is changed.It is important to note that the change in stoichiometry does not cause any change in the crystal structure.
