The ‘crystal lattice’ is the pattern formed by dots (represents the molecules) and used to represent the positions of these repeating structural elements in three-dimensional plane. This periodic and symmetric structure of an ideal crystal thus formed, is most easily described by “Lattice”. ...
WebA crystal lattice is made of points. A crystal system is a set of axes. In other words, the structure is an ordered array of atoms, ions or molecules. Crystal Structure is obtained by attaching atoms, groups of atoms or molecules. This structure occurs from the intrinsic nature of the constituent particles to produce symmetric patterns.
WebCrystallography is the experimental science of determining the arrangement of atoms in crystalline solids.
