← ScienceWhich outcome is observed when electron density shifts?
A)Change in the dipole moment✓
B)Increase in ionization energy
C)Vibrational mode excitation
D)Reduced nuclear binding energy
💡 Explanation
A change in electron density affecting the electron orbitals causes a change in **dipole moment**, because the asymmetrical distribution of charge leads to an uneven concentration of positive and negative regions. Therefore, the dipole moment changes, rather than inducing vibration.
