Ionization energy depends upon____________________?
Correct answer: D. I.E depends upon all of the above and nature of orbital
- A. Nuclear charge
- B. Atomic size
- C. Shielding effect
- D. I.E depends upon all of the above and nature of orbital
Explanation
Ionization energy depends on nuclear charge, atomic size, shielding, and the type of orbital from which the electron is removed, so all the listed factors matter. The likely distractor is a, nuclear charge, because it strongly affects ionization energy but cannot explain the complete trend without size, shielding, and orbital effects.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
