WebThere are basic classes of crystal defects: point defects, which are places where an atom is missing or irregularly placed in the lattice structure. Point defects include lattice vacancies, self-interstitial atoms, substitution impurity atoms, and interstitial impurity atoms. linear defects, which are groups of atoms in irregular positions. WebThe electron so trapped can absorb only certain colours of light. F-centres in sodium chloride absorb only blue light, giving the solid a yellow-orange tinge. Sodium chloride is usually colourless, however, because its electrons are not free to move to vacancies formed by removal of negative chloride ions from the solid.
