NEET Chemistry Ionization Energy MCQ Question
Consider a diagram depicting the ionization energy process for elements across the second period. Which factor primarily contributes to the increase in ionization energy from lithium to fluorine?
Increase in nuclear charge (Z)
Decrease in atomic mass
Increase in electron gain enthalpy
Decrease in valence principal quantum number (n)
Correct Answer
Detailed Explanation
As we move across the second period from lithium to fluorine, the nuclear charge increases, which results in a higher ionization energy due to the stronger attraction between the nucleus and the valence electrons.
