Question

Explain various types of defects in crystalline solids

Answer 1

Answer:

When the ideal arrangement of solids is distorted around an atom/point in a crystalline solid, it is referred to as a point defect. Imperfections or Defects present in a crystalline solid can be divided into 4 groups, namely: Line defects, Point defects, Volume defects, Surface defects.

Answer 2

Various types of defects in crystalline solids:

• Line defects- This kind of defect refers to the lines with which whole rows of atoms are arranged anomalously in a solid.
• Point defects- Point defects happen only at or around a single lattice point.

• Volume defects- This defect refers to the absence of a number of atoms in order to form internal surfaces in the crystal.

• Surface defects- This kind of defect separates material into regions that have the same crystalline structure. It doesnot have the same orientation.
