C)O
D)S

Question

Quizplus · Accepted Answer

Fluorine (F) has the highest first ionization energy among the options given. This is because it is the most electronegative element, meaning it has a strong tendency to attract electrons. Ionization energy increases across a period from left to right in the periodic table due to the increase in nuclear charge, which attracts the electrons more strongly and makes them harder to remove. Fluorine, being to the right of the others in the same period, has the highest first ionization energy.
