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.
