Ordered crystal structure
WebJan 26, 2024 · Crystal structure. In mineralogy and crystallography, a crystal structure is a unique arrangement of atoms in a crystal. Note: The above text is excerpted from the … WebBased on the angles and the length of the axes sides, unit cell can be divided into 6 crystal families, which are cubic, tetragonal, hexagonal, orthorhombic, monoclinic and triclinic. As the hexagonal family can have two different appearances, we can divide it into two systems which are trigonal lattice and hexagonal lattice.
