### Step-by-Step Text Solution **Step 1: Definition of Point Defects** Point defects are irregularities or imperfections that occur at specific points within the crystalline structure of a solid. These defects can arise due to the absence or presence of atoms at lattice points, which disrupts the ideal arrangement of the crystal lattice. **Step 2: Types of Point Defects** Point defects can be classified into two main types: 1. **Stoichiometric Defects** ...

Defects are basically irregularities in the arrangement of constituent particles. Broadly speaking the defects are of two types. Namely point defects and line defects. Point defects: The irregularities or deviations from ideal arrangement around a point or an atom in the crystalline substance. Line defects : The irregularities or deviations from ideal arrangement in enitre row of lattice points. Answer the following questions.
