WebThe symmetry observed in crystals as exhibited by their crystal faces is due to the ordered internal arrangement of atoms in a crystal structure, as mentioned previously. This arrangement of atoms in crystals is called a lattice . In 2-dimensions a plane lattice consists of an orderly array of points. WebCrystallography is the experimental science of determining the arrangement of atoms in crystalline solids.Crystallography is a fundamental subject in the fields of materials science and solid-state physics (condensed matter physics).The word crystallography is derived from the Ancient Greek word κρύσταλλος (krústallos; "clear ice, rock-crystal"), with its …
