Question

Quizplus · Accepted Answer

Chlorine (Cl) has the highest ionization energy due to its high electronegativity and small atomic size, so it matches with 1255 kJ/mol. Potassium (K) has the lowest ionization energy because it is an alkali metal, so it matches with 418 kJ/mol. Germanium (Ge) falls in between, matching with 784 kJ/mol.
