radicals that remain intact during chemical reaction are holistic molecular fragments;
the way in which atoms stack together in molecules or radicals depend on the electronic configuration of the elements concerned;
molecular shape — left undefined by Kekulé — can be ascribed to the minimization of orbital angular momentum.
