Difference between space lattice and crystal …

The position of atoms, molecules, or ions in a solid crystal, relative to one other in space, is usually designated by points. Such a representation is called space lattice. Thus, we define the space lattice as an array of points showing how molecules, atoms or ions are arranged at different sites in three-dimensional spaces. Its dimensions along the three edges may or may not be mutually perpendicular.
Crystal Lattice is a three-dimensional representation of atoms and molecules arranged in a specific order/pattern. In other words, a crystal lattice can be defined as a geometrical arrangement of constituent particles of matter (atoms, ions or molecules) as points in space. There are total 14 possible three-dimensional lattices. Crystal lattices are also known by Bravais Lattices, named after the scientist Auguste Bravais. Each point in a lattice represents a lattice site or we can say lattice point.  Each point denotes a particular type of constituent particles of matter be it an atom, molecule or an ion.By joining the lattices points inside the lattice we can define geometry of the lattice
