The diference between covalent molecule lattice and covalent network lattice Can you tell me the difference between covalent molecular lattice and covalent network lattice?
Thanks for your help.
Covalent molecular compounds are actual molecules. Examples include $\ce{H_2O, NH_3, CO_2, N_2, I_2, SO_3, N_2O_4}$ etc. They are made of molecules which are made of covalently bonded atoms. Covalent network compounds form a network of bonds, and the whole object can almost be considered a "molecule," such as diamond (C network), silicon (Si network), graphene (C network), and black phosphorous (P network).

It's not a coincidence that all but one of the covalent molecules that I listed are gasses at room tenperature and pressure. The intermolcular bonds between molecules are relatively weak. On the other hand, every molecule in a network solid is surrounded in a network of strong covalent bonds.
