Short Range and Long Range Order(SOLID STATE)
Short range order refers to the regular and predictable arrangement of the atoms over a short distance, usually with one or two atom spacings. However, this regularity does not persist over a long distance. ... Besides ordering of atoms, short-range ordering of vacancies are also possible.
In long range order, as in crystalline solids, there is a regular pattern of arrangement of particles which repeats itself periodically over the entire crystal. In other words, a solid is considered crystalline if it has long range order
