Crystallography MCQ

Crystallography Definition 

Crystallography is the experimental science of determining the arrangement of atoms in crystalline solids. The word “crystallography” is derived from the Greek words crystallon “cold drop, frozen drop”, with its meaning extending to all solids with some degree of transparency, and graphein “to write”.
