Molecular |
ionic |
Molecular crystals are made of molecules and are held by weak dispersion force or dipole - dipole interaction so are soft and melt easily. They are soft and insulators as there are no charged particle to conduct electricity. As the Binding energy holding the molecule is weak they have low melting point. Like ice &sugar.

The most common type of crystal is ionic made of ions bonded to each other by ionic bond. All salt that you see and analyze are ionic with high binding energy and melting point. Like NaCl, KBr and KI. |
