Two atoms approach until the potential energy of the pair is at its lowest. That separation defines the:
ABond length
BBond dipole
CBond angle
DBond order
Answer & Solution
Correct answer: A. Bond length
1. Too far apart and attraction is wasted; too close and the nuclei repel.
2. In between lies a distance where the energy dips lowest.
3. That internuclear distance is the bond length.
