In a stable molecule potential energy of the system is:
Correct answer: C. Minimum
- A. Moderate
- B. Variable
- C. Minimum
- D. Maximum
Explanation
A molecule is most stable or least reactive in its lowest energy state. As two atoms approach each other in an effective collision, strong repulsive forces develop between them and their potential energies increase. This is a highly unstable state in which the atoms are most likely to react.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
