However, in covalent bonds, the valence electrons from both of the two atoms are shared between two atoms. Thus, neither atom is given a full positive or negative charge. Instead, the electrons shared between the two atoms-whether it be 2, 4, or 6 electrons-varies from molecule to molecule.There are two types of covalent bonds: pure covalent bonds and polar covalent bonds.ach covalent bond consists of two electrons, one usually from each atom involved in the bond. The atoms form enough covalent bonds that when the electrons in the bonds are added with the valence electrons, they will have an octet.
