Sodium chloride crystals are composed of sodium and chlorine ions held together by electrostatic attraction. Each sodium ion is surrounded by six chlorine ions, and each chlorine ion is surrounded by six sodium ions. A crystal builds up like this, giving the sodium chloride crystal a cubic structure.

Graphite has a layered, planar structure. In each layer, the carbon atoms are arranged in a honeycomb lattice with separation. The layering contributes to its lower density. Within the layer, the carbon atoms are held by the strong covalent bonds but between the layers we have the weak Van der Waals...

Each silicon atom can bond to 4 oxygen atoms, and this gives rise to a giant covalent network structure which each Si is bonded to four oxygens and each 0 to two silicon atoms. Again, the bonding between the atoms goes on and on in three dimensions.Silicon dioxide is insoluble in water and has a ver...
