WebA crystal lattice is a three-dimensional depiction of atoms and molecules organised in a specific order or pattern. A crystal lattice may be described as the spatial arrangement of constituent particles of matter (atoms, ions, or molecules) as points in space. Each point represents a different element of the crystal. WebUnit Cell is the smallest part (portion) of a crystal lattice. It is the simplest repeating unit in a crystal structure. The entire lattice is generated by the repetition of the unit cell in different directions. 1. Parameters of a Unit …
