WebLATTICE: Translationally periodic arrangement of POINTS in space. BASIS (or MOTIF): An atom or a group of atoms associated with each lattice point in crystal. CRYSTAL=LATTICE+BASIS LATTICE of a crystal tells how to repeat (the periodicity of the crystal). BASIS tells what to repeat according to the lattice to get the crystal. WebJun 10, 2015 · Fig. Crystal structure with lattice point (A) and basis (A-B). +6 Fig. Primitive cell (a 1 , a 2 , a 3 ) and conventional cell (a x , a y a z ) for the fcc lattice.
WebA crystal structure is made of atoms. A 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 ... WebSep 9, 2016 · The Bravais lattice theory establishes that crystal structures can be generated starting from a primitive cell and translating along integer multiples of its basis vectors, in all directions. Snapshot 1: This shows the primitive cubic system consisting of one lattice point at each corner of the cube.
