The same as in the lineal molecules, the common bond for the hexa-molecules can also be used as covalent bond by other atoms or tetra-molecules that want to unite to this hexa-molecule.
Carbon Has 4 electrons in its outer energy level Can form covalent bonds with up to 4 other atoms Can form chains or rings with single, double, or triple bonds Monomers and Polymers Monomers are small molecules that can be linked together By forming covalent bonds between the monomers, larger molecules-called Polymersare formed.
M Effects -The electron displacement through covalent bonds determines the polarity of the molecule which in turn affect the physical properties (solubility and volatility) and chemical properties of the organic compound.

Water is a polar molecule • The electrons in the covalent bonds are not shared equally • This results in a water molecule with a negative end and a positive end.

For the joining of atoms, formation of covalent bonds, of molecules, crystals, and all type of materials is necessary that the fields of force that surround atoms are aligned in the appropriate direction N-S and this way they can unite to form fields of forces common for all them.
The SHAKE algorithm (35) was used for covalent bonds involving hydrogen atoms enabling integration time steps of 2 fs.
These molecules form covalent bonds with the silica surface  thus providing relatively stable surfaces, known as self-assembled monolayers (SAMs) or silanized surfaces.
Five Categories of Crystals Type of Crystal ionic homopolar bounded (covalent) metallic molecular hydrogen bonded substances alkali halides, alkaline oxides, etc.
The deterioration of the matrix created by biomolecules that do not form covalent chemical bonds with the underlying substrate is observed in cultures that extend beyond three days [22, 23].

The light blue region is representative of materials held together by strong intermolecular forces such as covalent bonds in metals.
