The electrons on the outermost energy level of the atom are called valence electrons. The valence electrons are involved in bonding one atom to another. The attraction of each atomâs nucleus for the valence electrons of the other atom pulls the atoms together. As the attractions bring the atoms together, electrons from each atom are attracted to the nucleus of both atoms, which âshareâ the electrons.
The bonds between carbon and hydrogen atoms are also nonpolar, such as the four CâH bonds in a methane molecule (Figure 2.5 d). In a polar covalent bond , the sharing of electrons between two atoms is unequalâthe nucleus of one atom attracts the shared electrons more strongly than the nucleus of the other atom. When polar covalent bonds form, the resulting molecule has a partial negative charge near the atom that attracts electrons more strongly.
