Detailed explanation-1: -There are 7 crystals systems and they are named: Triclinic, Monoclinic, Orthorhombic, Tetragonal, Trigonal, Hexagonal, and Cubic .
Detailed explanation-2: -There are seven types of crystal system and 14 types of Bravais lattices. Reason: Rhombohedral, triclinic and hexagonal crystal systems have only primitive unit cells.
Detailed explanation-3: -These additional lattice points divide the 7 crystal systems into 14 Bravais lattices; the Bravais lattices are subdivided into 32 crystal classes, or point groups.
Detailed explanation-4: -Triclinic System: It is the most unsymmetrical crystal system. Monoclinic System: It comprises three axes where two are at right angles to each other, and the third axis is inclined. Orthorhombic System: Trigonal System: Hexagonal System: Tetragonal Systems: Cubic System:
