Maximum ionization potential is of:
Correct answer: C. Be
- A. Ca
- B. Na
- C. Be
- D. Mg
Explanation
Ionization potential or ionisation potential is the amount of energy required to remove an electron from an isolated gaseous atom to form a cation. It increases across the period from left to right, and decreases down the group in the periodic table. So, the element which is towards the most right and top will have maximum ionisation potential ie Be in this case.

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.
