← ScienceWhich outcome prevents electron promotion in stable noble gases?
A)High ionization energy threshold✓
B)Sufficient nuclear shielding effect
C)Significant electron spin coupling
D)Zero permanent dipole moment
💡 Explanation
High ionization energy prevents electron promotion from filled valence orbitals, because *ionization energy* is the energy required to remove an electron; therefore, energy is insufficient to permit electron excitation, rather than spin coupling determining stability.
