How are point defects defined in crystalline substances?
Options
- AAs irregularities in entire rows of lattice points
- BAs deviations from the ideal arrangement around a point or an atom
- CAs surface imperfections in the crystal
- DAs dislocations in the crystal structure
Correct answer
B. As deviations from the ideal arrangement around a point or an atom
Step-by-step solution
Point defects in crystalline substances are defined as deviations from the ideal arrangement around a point or an atom in the crystal lattice.
