Which ionization process requires the most energy? A)S(g)→ S⁺(g)+ e^- B)S⁺(g)→ S²⁺(g)+ e^- C)Cl(g)→ Cl⁺(g)+ e^- D)Cl⁺(g)→ Cl²⁺(g)+ e^-

Question

Quizplus · Accepted Answer

The second ionization energy is always higher than the first because it requires removing an electron from a positively charged ion, which is more difficult due to increased electrostatic attraction. Among the given options, D involves the second ionization of chlorine, which requires the most energy.
