Explanation

A soild is said to be crystalline if its various constituent particle (i.e, atoms,ions, or molecules) are arranged in a defintie geometric pattern in three dimensional space so that there is short range as well as long range order of constituent particles, Due to well defined ordered structure in three dimensions, crystals give a clean cleavage on being cut with a sharp knife.
