Ch. 3 - 2 Potential energy exists between objects that either attract or repel each other. In the case of atoms joined by a covalent bond, the lowest potential energy state occurs when atoms are at their ideal internuclear distance (bond length). Lengthening or shortening the bond distance raises the potential energy.
