Vacancy defects in solids is a subtype of ______
Vacancy defects in solids is a subtype of ______
Right Answer is:
Point imperfections
SOLUTION
Vacancy defects in solids are a subtype of point imperfections.
- Point defects, as the name implies, are imperfect point-like regions in the crystal.
- The typical size of a point defect is about 1-2 atomic diameters.
- Sometimes it is also known as an intrinsic or thermodynamic defect.
Vacancy defect:
- When an atom is not present at their lattice sites, then that lattice site is vacant and it creates a vacancy defect.
- Due to this, the density of a substance decreases.
