Definition
A space lattice is a three-dimensional arrangement of points representing the periodic structure of a crystalline solid. These points correspond to the positions of atoms, ions, or molecules within the crystal.
5 Must Know Facts For Your Next Test
Space lattices are characterized by their repeating patterns in three dimensions.
They form the basis for understanding crystal structures and their properties.
Common types of space lattices include cubic, tetragonal, orthorhombic, hexagonal, monoclinic, triclinic, and rhombohedral.
The smallest repeating unit in a space lattice is called the unit cell.
The arrangement and bonding within a space lattice determine many physical properties of solids such as density, hardness, and melting point.
The smallest repeating unit in a crystal lattice that defines its structure.
Crystal Lattice: A synonym for space lattice; it describes the ordered arrangement of atoms or molecules in a crystalline solid.
$Bravais\ Lattices$: $14$ distinct three-dimensional geometric arrangements that can be used to describe all possible periodic arrangements of points in space.
