Question

if lattice points are missing in vacancy defects, shouldn't this disturb the stoichiometry of the compound? ​

Answer 1

Answer:

The defects in crystals which do not disturb the stoichiometry of the compound or crystal are called stoichiometric defects. It results in a decrease in density of the substance. Number of vacancy defects depends on the temperature of the crystal. It occurs due to imperfect packing during crystallization.
