Question

define impurity defect in chemistry​

Answer 1

Answer:

In crystal defect. Impurity defects are foreign atoms that replace some of the atoms making up the solid or that squeeze into the interstices; they are important in the electrical behaviour of semiconductors, which are materials used in computer chips and other electronic devices.

Explanation:

Answer 2

impurity defect:--

if molten NaCl containing a little amount of SrCl2 is crystallized,some of the sites of Na+ions are occupied by Sr2+ . each Sr2+ replaces two Na+ions . it occupies the site of one ion and the other site remains vacant. the cationic vacancies thus produced are equal in number to that of Sr2+ ions. another similar example is the solid solution of CdCl2 and AgCl.
