When two atoms are equally electronegative, they will interact to form a nonpolar covalent bond. In this type of bond, the electrons are shared equally between the two atoms because both have the same tendency to attract the bonding pair of electrons. This is typically seen when two atoms of the same element bond together, such as in H2 or Cl2 molecules. The bond is considered a "pure" covalent bond because the shared electrons are evenly distributed between the two atoms.
