Crystal Lattice and Unit Cell in Solid State Chemistry
Explore the concept of crystal lattice and unit cell in solid state chemistry taught by instructor U. Nithya M.Sc., M.Phil. Crystal lattice is the arrangement of constituent particles in three dimensions, while a unit cell is defined by six parameters including edges and angles. Dive into the characteristics and parameters of crystal structures for a deeper understanding of crystalline solids.

SOLID STATE Name of the instructor: U.Nithya M.Sc.,M.Phil.,
CRYSTAL LATTICE: Crystal lattice is the depiction of three dimensional arrangements of constituent particles (atoms, molecules, ions) of crystalline solids as points. Or the geometric arrangement of constituent particles of crystalline solids as point in space is called crystal lattice. Characteristics of crystal lattice: Each constituent particle is represented by one point in a crystal lattice. These points are known as lattice point or lattice site. Lattice points in a crystal lattice are joined together by straight lines. By joining the lattice points with straight lines the geometry of the crystal lattice is formed.
Parameters of a unit cell: A unit cell is characterized by six parameters. These parameters are three edges (a, b and c) and angles between them ( , and ). Dimensions along the edges of a unit cell is represented by a, b and c. Edges of unit cell may or may not be mutually perpendicular. The angle between b and c is represented by , between a and c by and between a and b by .
