Question

In a crystal lattice what are the vacancy created in the absence of certain atom is known ascrystal defects

Answer 1

Answer:-

In vacancy defects one or more type of the constituent atoms are missing due to the absence of them from their interstitial positions. it generally consists of 2 types-

Metal deficiency defects involve 1 metal atom leaving only.

In a crystal lattice when oppositely charged anions leave their interstitial positions, leaving behind vacancies these are called schottky defect. This is a stoichiometric defect, with the chemical formula remaining same. But the density decreases.
