Summary and Contents
The solids in which the atoms, ions and molecules are arranged periodically are called crystalline solids.The crystalline solids show the phenomenon of X-ray diffraction.Every crystalline solid has sharp melting point i.e., for every crystal there is a temperature at which the thermal vibrations becomes so great that the structure suddenly breaks up, and the solid melts.
