There are 7 crystals systems and they are named: Triclinic, Monoclinic, Orthorhombic, Tetragonal, Trigonal, Hexagonal, and Cubic..
What are the crystal models?
A crystal model is a teaching aid used for understanding concepts in crystallography and the morphology of crystals. Models are ideal to learn recognizing symmetry elements in crystals. Crystal models at Musée de minéralogie..
What is a crystalline model?
A crystal model is a three-dimensional representation of a crystal lattice structure, used to visualize the arrangement of atoms or molecules within the crystal..
To use this technique, the crystallographer obtains protein crystals, records the diffraction pattern formed by x-rays passed through the crystals, and then interprets the data using a computer. The result is a atomic-resolution model of a protein.
The model names are:
Cubic (sometimes called isometric)
Tetragonal.
Orthorhombic.
Trigonal.
Hexagonal.
Monoclinic.
Triclinic.
Calcite.

Merritt. The information describing a final crystallographic model is composed of: Data from the diffraction experiment: wavelength and diffraction pattern (
Can crystal structure databases and visualization software improve the teaching of Crystallography?
We believe that the full potential of crystal structure databases and visualization software for enhancing the teaching of crystallography has not been fully explored
In most mineralogy classes, such tools are used to illustrate concepts in crystallography and crystal-chemistry, but these sessions are mostly controlled by the instructor
Quantitative crystallography began with Carangeot's invention of the contact goniometer (1780)
Crystallography models
Method of protein structure prediction using other known proteins
Homology modeling, also known as comparative modeling of protein, refers to constructing an atomic-resolution model of the target protein from its amino acid sequence and an experimental three-dimensional structure of a related homologous protein. Homology modeling relies on the identification of one or more known protein structures likely to resemble the structure of the query sequence, and on the production of an alignment that maps residues in the query sequence to residues in the template sequence. It has been seen that protein structures are more conserved than protein sequences amongst homologues, but sequences falling below a 20% sequence identity can have very different structure.
In chemistry
Type of 3D molecular model
In chemistry, a space-filling model, also known as a calotte model, is a type of three-dimensional (3D) molecular model where the atoms are represented by spheres whose radii are proportional to the radii of the atoms and whose center-to-center distances are proportional to the distances between the atomic nuclei, all in the same scale. Atoms of different chemical elements are usually represented by spheres of different colors.
