Covalent bond crystal
Webresponsible for the stability of the crystal. There are several types of bonding, depending on the physical origin and nature of the bonding force involved. The four main types are: Van der Waals (or molecular) bonding, ionic bonding, covalent bonding and metallic bonding. WebIn polymers, there are covalent bonds between the atoms of the polymer, but the polymeric macromolecules (or chains) are kept together by Van der Waals forces. Of all the four types of bonds, Van der Waals is the weakest. ... Due to these differences (e.g., multiple crystals with various orientations, presence of grain boundaries, fabrication ...
