The ionization energy of groups _ shows an abnormal trend?
Correct answer: D. 3A and 6A
- A. 3A & 4A
- B. 5A & 6A
- C. 6A & 4A
- D. 3A and 6A
Explanation
The ionization energies of group IIIA and VIA show abnormal trends because elements of these groups tend to lose electrons easily to become stable.

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.
