WebApr 8, 2024 · Metal deficiency defect – This is a type of defect caused when a metal ion or cation is missing from its lattice site. Whenever such a type of defect occurs, the electrical neutrality is maintained by one of the nearest cations which acquires an extra positive charge. This is possible in crystals which are made of metals with variable valency.
